  • 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 Trinket Mini Microcontroller 5V Logic (#1501)
    Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's our lowest-cost arduino-IDE programmable board!

    The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Arduino board. You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform.

    This is the 5V Trinket. There are two versions of the Trinket. One is 3V and one is 5V. Both work the same, but have different operating logic voltages. Use the 3V one to interface with sensors and devices that need 3V logic, or when you want to power it off of a LiPo battery. The 3V version should only run at 8 MHz. Use the 5V one for sensors and components that can use or require 5V logic. The 5V version can run at 8 MHz or at 16MHz by setting the software-set clock frequency.

    Even though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. There are some things you trade off for such a small and low cost microcontroller!
    • Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data
    • Some computers' USB v3 ports don't recognize the Trinket's bootloader. Simply use a USB v2 port or a USB hub in between
    Here are some useful specifications!
    • ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM
    • Internal oscillator runs at 8MHz, but can be doubled in software for 16MHz
    • USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude (with a simple config modification) and/or the Arduino IDE (with a few simple config modifications)
    • Mini-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.
    • We really worked hard on the bootloader process to make it rugged and foolproof, this board wont up and die on you in the middle of a project!
    • ~5.25K bytes available for use (2.75K taken for the bootloader)
    • Available in both 3V and 5V flavors
    • On-board 3.3V or 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 #1 LED
    • Reset button for entering the bootloader or restarting the program. No need to unplug/replug the board every time you want to reset or update!
    • 5 GPIO - 2 shared with the USB interface. The 3 independent IO pins have 1 analog input and 2 PWM output as well. The 2 shared IO pins have 2 more analog inputs and one more PWM output.
    • Hardware I2C / SPI capability for breakout & sensor interfacing.
    • Works with many basic Arduino libraries including Adafruit Neopixel!
    • Mounting holes! Yeah!
    • Really really small

  • FLORA - Wearable electronic platform: Arduino-compatible (#659)
    For the last few years Ladyada has been thinking about everything she wanted in a wearable electronics platform for Adafruit's community of makers, hackers, crafters, artists, designers and engineers. After months of planning, designing and working with partners around the world for the best materials and accessories, we can share what we're up to. The hardware is now shipping! We call it the FLORA.

    Adafruit created the FLORA from scratch after many months of research and we really think we came up with something that will empower some amazing wearable projects.

    The FLORA is small (1.75" diameter, weighing 4.4 grams). We wanted the smallest possible board for our wearable platform. In the FLORA family we also have the best stainless steel threads, sensors, GPS modules and chainable LED pixels, perfect accessories for the FLORA mainboard

    The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up - all you need is a USB cable, no additional purchases are needed! Works with Mac, Windows, Linux, any USB cable works great. Currently the PCB comes with a mini B connector but future versions may change to microUSB. The FLORA has USB HID support, so it can act like a mouse, keyboard, MIDI, etc. to attach directly to cellphones.

    The FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is designed to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric. We suggest a micro LiPo charger if you want to use LiPo batteries with FLORA

    The FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. Often FETs are not included in other designs that leads to switch failure as small SMT switches are rated for only 20mA current use. The FLORA has an onboard 3.3v 100mA regulator with protection diode and USB fuse so that power is consistent and can power common 3.3v modules and sensors.

    We spent a lot of time on the power supply because the FLORA power system is specifically designed to allow easy control and power of a large quantity of digital RGB LED pixels such as the FLORA pixel series of accessories.

    The FLORA is fabric friendly. The FLORA does not use FTDI headers (built in USB support) headers of any kind sticking out can grab and tear fabric.

    The FLORA is extremely beginner-friendly - it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The on-board regulator means that even connecting a 9V battery will not result in damage or tears.

    The FLORA has 4 indicator LEDs: power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users.

    There are 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread.

    The FLORA works with the Adafruit-fixed Leonardo-like bootloader and will work with any future released Leonardo-compatible bootloader. FLORA is currently using our bootloader and Adafruit USB vendor ID.

    The FLORA comes with Adafruit's support, tutorials and projects. Adafruit has dozens of projects that will be released with the FLORA in 2013 and has staff 100% dedicated to creating tutorials and projects for use with the FLORA.

    The FLORA is not the first wearable Arduino / Arduino-compatible. Leah Buechley’s Lilypad was developed in 2007 – we wanted to also make something that’s wearable, but it needed to be a completely new platform for our accessories/modules and goals for the project.

    The FLORA is made in NYC at Adafruit, it was designed by Limor Fried (Ladyada) she is an Electrical Engineer with a proven track record of providing over 26 high-quality libraries for Arduino/Arduino IDE, over 100 tutorials, open-source code and contributions to the Arduino project. She was a member of the MIT wearables group and likes to sew.
