  • Adafruit Monochrome 0.96" 128x64 OLED Graphic Display (ADA326)

    Monochrome 0.96" 128x64 OLED graphic display

    These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

    The driver chip, SSD1306 can communicate in two ways: I2C or SPI. The OLED itself require a 3.3V power supply and 3.3V logic levels for communication, but we include a 3.3V regulator and all pins are fully level shifted so you can use with 5V devices!

    The power requirements depend a little on how much of the display is lit but on average the display uses about 40mA from the 3.3V supply. Built into the OLED driver is a simple switch-cap charge pump that turns 3.3v-5v into a high voltage drive for the OLEDs.

    Adafruit have a detailed tutorial and example code in the form of an Arduino library for text and graphics. You'll need a microcontroller with more than 1K of RAM since the display must be buffered. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 1K of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.

    • PCB: 38mm x 29mm (1.5" x 1")
    • Screen: 25mm x 14mm
    • Thickness: 4mm
    • Weight: 8.5g
    • Display current draw is completely dependent on your usage: each OLED LED draws current when on so the more pixels you have lit, the more current is used. They tend to draw ~20mA or so in practice but for precise numbers you must measure the current in your usage circuit.
    • This board/chip uses I2C 7-bit address between 0x3C-0x3D, selectable with jumpers

  • Adafruit NeoPixel Quarter 60 Ring - 15 x WS2812 5050 RGB LED with Integrated Drivers (ADA-QRING15)

    Adafruit NeoPixel Quarter Ring - 15 x WS2812 5050 RGB LEDs (Model #1768)

    The biggest NeoPixel Ring yet! With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2" diameter. Each order comes with just the quarter ring. Four of this item are required to make a large ring. You will have to solder them together as well, so for the full ring of 60 LEDs, buy four and solder them together!

    The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.

    There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

    Comes with one quarter ring of 15 x individually addressable RGB LEDs assembled and tested. We recommend you buy four to build the full circle as this is just the 1/4 of the circle.

  • Adafruit Trinket Pro 5V Logic (ADA2000)

    Trinket's got a big sister in town - the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in, so delicious.

    Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That's why Adafruit designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.

    Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends.

    The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs much of the same capability as an Arduino UNO. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller.

    The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. at the same speed and voltage. So you'll be happy to hear that not only is Pro Trinket programmable using the Arduino IDE as you already set up, but 99% of Arduino projects will work out of the box!

    For tons more details, check out the Introducing Pro Trinket tutorial

    Here's some things you may have to consider when adapting Arduino sketches:

    • Pins #2 and #7 are not available (they are exclusively for USB)
    • The onboard 5V regulator can provide 150mA output, not 800mA out
    • You cannot plug shields directly into the Pro Trinket
    • There is no Serial-to-USB chip onboard. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. The USB connection is for uploading new code only.
    • The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes. The bootloader does not affect RAM usage.

    Here's some handy specifications:

    • ATmega328P onboad chip in QFN package
    • 16MHz clock rate, 28K FLASH available
    • USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).
    • Also has headers for an FTDI port for reprogramming
    • Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.
    • On-board 5.0V power regulator with 150mA output capability and ultra-low dropout. Up to 16V input, reverse-polarity protection, thermal and current-limit protection.
    • Power with either USB or external output (such as a battery) - it'll automatically switch over
    • On-board green power LED and red pin #13 LED
    • Reset button for entering the bootloader or restarting the program.
    • Works with 99% of existing Arduino sketches (anything that doesn't use more than 28K, and doesn't require pins #2 and #7)
    • Mounting holes! Yeah!

  • Adafruit NeoPixel Jewel - 7 x WS2812 5050 RGB LED with Integrated Drivers (ADA-2226)

    Adafruit NeoPixel Jewel - 7 x WS2812 5050 RGB LEDs (Model #2226)

    Be the belle of the ball with the NeoPixel Jewel!  We fit seven of our the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant (and evening-wear appropriate) NeoPixel board yet.
    Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.

    The LEDs are 'chainable' by connecting the output of one Jewel into the input of another. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

    Comes as a single round board with 7 individually addressable RGB LEDs assembled and tested.

    Adafruit's NeoPixel Uberguide has everything you need to use NeoPixels in any shape and size. Including ready-to-go library & example code for the Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due & Arduino Mega/ADK (all versions)

  • Adafruit Perma-Proto HAT for Pi Mini Kit - With EEPROM (ADAHATI)

    Description

    Design your own Raspberry Pi HAT, attach custom circuitry and otherwise dress your Pi A+ or B+ with this jaunty prototyping HAT kit with EEPROM

    To kick off the Adafruit HAT party, we have this Perma-Proto inspired plug in daughter board. It has a grid of 0.1" prototyping soldering holes for attaching chips, resistors, LED, potentiometers and more. The holes are connected underneath with traces to mimic the solderless breadboards you're familiar. There's also long power strips for +3V, +5V and Ground connections to the Pi. Near the top we break out nearly every pin you could want to connect to the Pi (#26 didnt quite make the cut).

    This is the fancier version of our Perma-Proto HAT.  It comes with a printed circuit board and a single 2x20 GPIO Header for Raspberry Pi to put your Perma-Proto on top of your Raspberry Pi (like a nice little hat...) This version comes with a blank 24C32 I2C EEPROM soldered on and connected to the EEDAT/EECLK lines so you cannot 'stack' it with other HATs. However, you can program in the EEPROM to make a self-identifying setup using the Pi Foundations' HAT specs - please note the specifications are still under development.

    You can customize your Perma-Proto setup using a standard 2x20 stacking header or extra tall 2x20 stacking header.

    A bit of light soldering is required to attach the header to the PCB but it's easy work.

    This hat is only compatible with the Raspberry Pi B+ or A+! It will not work with the Raspberry Pi Model A or B.

    The version we are shipping has the +3V and +5V markings in Red, and the GND markings in Blue

  • Adafruit Ultimate GPS HAT for Raspberry Pi (ADAGPSHAT)

    Description

    It's 10PM, do you know where your Raspberry Pi is? If you had this GPS HAT, you would! This new HAT from Adafruit adds their celebrated Ultimate GPS on it, so you can add precision time and location to your Raspberry Pi Model A+, B+, or Pi 2

    Here's the low-down on the GPS module:

    • -165 dBm sensitivity, 10 Hz updates, 66 channels
    • Only 20mA current draw
    • Built in Real Time Clock (RTC) - slot in a CR1220 backup battery for 7-years or more of timekeeping even if the Raspberry Pi is off!
    • PPS output on fix, by default connected to pin #4
    • Internal patch antenna which works quite well when used outdoors + u.FL connector for external active antenna for when used indoors or in locations without a clear sky view
    • Fix status LED blinks to let you know when the GPS has determined the current coordinates

    Adafruit spun up a HAT based on their Ultimate GPS, added a coin-cell holder for RTC usage, break-outs for all the Raspberry Pi's extra pins, and plenty of prototyping area for adding LEDs, sensors, and more.

    Please note, this HAT takes over the Raspberry Pi's hardware UART to send/receive data to and from the GPS module. So, if you need to use the RX/TX pins with a console cable, you cannot also use this HAT. Instead, you'll have to use a composite or HDMI monitor and keyboard to log in, or use ssh to connect over the network to your Pi. Read up on Adafruit's tutorial for more information on how to use this fine HAT

    Comes as a fully assembled GPS + PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder.

    This HAT does not come with a 12mm coin battery! A CR1220 will let you use the real-time-clock capability of the GPS HAT

  • Adafruit 12 x Capacitive Touch HAT for Raspberry Pi (ADACAPHAT)

    Description

    This touch-able add on HAT for Raspberry Pi will inspire your next interactive project with 12 capacitive touch sensors. Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes. Capacitive touch sensing used for stuff like touch-reactive tablets and phones, as well as control panels for appliances, which is where you may have used it before. This HAT allows you to create electronics that can react to human touch, with up to 12 individual sensors.

    The HAT has 12 'figure 8' holes in it that can be gripped onto with alligator clip cables. Attach one side of the clip to the HAT and the other side to something electrically conductive (like metal) or full of water (like vegetables or fruit!) Then start up our handy Python library code to detect when the object is touched. That's pretty much it, very easy! For advanced users, you can also solder to a pad to make a slimmer & more permanent connection.

    Works great with Raspberry Pi Model A+, B+, or Pi 2. This HAT can be used with Model A or Model B but requires purchase/soldering of a extra-tall 2x13 header instead of the 2x20 included.

    Adafruit  are working on a detailed tutorial, meanwhile you can check out the tutorial for the non-HAT/breakout-version of this chip with the Raspberry Pi here which uses the exact same library and code. We have examples for reading touches, turning touches into keyboard KeyUp/KeyDown presses (so you can make a veggie-keyboard) as well as an audio player that will play a sound per sensor (fruit drums!)

    Each order comes with a Capacitive Touch HAT and a 2x20 socket header. You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but its easy to do with basic soldering tools like a soldering iron and rosin core electronics solder.

    Please note! This kit does not come with Raspberry Pi, alligator clips, speaker, or delicious fruit!

  • Adafruit Bluefruit LE - Bluetooth Low Energy (BLE 4.0) - nRF8001 Breakout - v1.0 (ADABLE)

    Description

    The Adafruit Bluefruit LE (Bluetooth Smart, Bluetooth Low Energy, Bluetooth 4.0) nRF8001 Breakout allows you to establish an easy to use wireless link between your Arduino and any compatible iOS or Android (4.3+) device. It works by simulating a UART device beneath the surface, sending ASCII data back and forth between the devices, letting you decide what data to send and what to do with it on either end of the connection.

    Unlike classic Bluetooth, BLE has no big contracts to sign and no major hoops that you have to jump through to create iOS peripherals that you can legally design and distribute in the App Store, which makes it a great choice compared to classic Bluetooth which had (and still has) a lot of restrictions around it on the iOS platform.

    And now that Android also officially supports Bluetooth Low Energy (as of Android 4.3), it's also -- finally! -- a universal communication channel covering the main mobile operating systems people are using today.

  • Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (ADASERVOHAT)

    Description

    The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.

    For use with Raspberry Pi Model A+, B+, or Pi 2 can be used with the Model A or B if you use a tall 2x13 header instead of the included 2x20.

    The Adafruit 16-Channel 12-bit PWM/Servo HAT will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What's more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins!

    Best of all, we even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs! Please check out this detailed tutorial for lots more information including diagrams, schematics, installation instructions and more

    Each order comes with a Servo HAT, a 2-pin terminal block, four 3x4 headers and a 2x20 socket header. You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but its easy to do with basic soldering tools like a soldering iron and rosin core electronics solder. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.

    Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply
