  • PiStep2 Dual/Quad Stepper Motor Control Board for Raspberry Pi (PISTEP2D/Q)

    Dual/Quad Stepper Motor Control Board for Raspberry Pi

    Fully Assembled - No Soldering Required

    Raspberry Pi Zero Form Factor - works with all versions of Raspberry Pi with 40pin GPIO connector

    Stepper motors (optional extra) and Raspberry Pi not included


    Available in either Dual (2 steppers) or Quad (4 steppers) versions

    Various Power Options:
    1. Powered from the Raspberry Pi 5V
    2. From the 2-pin Terminal (whatever voltage is required for the motors)
    3. Micro-USB - 5V only
    This neat little board plugs directly into the Raspberry Pi GPIO header and provides 2 or 4 connectors for our small stepper motors 28BYJ-48

    Pinout is simple:
    • Physical pins 11, 12, 13, 15 for Motor A (GPIO 17, 18, 27, 22)
    • Physical pins 16, 18, 22, 7 for Motor B (GPIO 23, 24, 25, 04)
    • Physical pins 33, 32, 31, 29 for Motor C (GPIO 13,12,6,5)
    • Physical Pins 38, 37, 36, 35 for Motor D (GPIO 20,26,16,19)
       

    Each pin has an associated white LED so you can see the stepper signals going through

    Power Supply Alternatives

    • Jumper VCC-VSTP (default). Power from the motors is taken from the Raspberry Pi 5V line
      • Micro-USB into Raspberry Pi. 5V for the Pi and the stepper motors goes through a poly-fuse which can trip if 2 motors are used simultaneously
      • Micro-USB into the PiStep board. 5V for both the Pi and the stepper motors is provided directly from the 5V USB input so no problems with 2 motors at once
    • Jumper VSTP-VIN. Power for the motors is provided from the 2-pin screw terminal, so can be any voltage that the steppers can handle. Ensure you use the correct polarity! We recommend to keep it below 12V. You will find that the stepper motors can go up to 9V and will be able to step faster, the higher the voltage that is applied, but there will be some deterioration of the life of the stepper motor at a higher voltage.



    Python Programming
    Please see the excellent example here for some pointers. You will need to change the pin numbers as above and also change the speed so it steps at a visible rate. You may also want to remove the print statements to speed it up. The lines in Red below are changed from the original to operate Motor A.

    # Use BCM GPIO references
    # instead of physical pin numbers
    GPIO.setmode(GPIO.BCM)

    # Define GPIO signals to use
    # Pins 18,22,24,26
    # GPIO24,GPIO25,GPIO8,GPIO7
    StepPins = [17,18,27,22]

    # Set all pins as output
    for pin in StepPins:
      print "Setup pins"
      GPIO.setup(pin,GPIO.OUT)
      GPIO.output(pin, False)

    # Define some settings
    StepCounter = 0
    WaitTime = 0.01



    ScratchGPIO Programming

    These pins are identical to those required by ScratchGPIO and therefore can easily be driven using simple Scratch commands:
    Set motor type for Scratch to be Stepper motor

    Set the position of the stepper motor A

    Set the speed of the stepper motor A

  • Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685 (#815)
    You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout.

    When we saw this chip, we quickly realized what an excellent add-on this would be. Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs (which we would really like to see since it would be glorious)
    • It's an i2c-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
    • It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
    • 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
    • Adjustable frequency PWM up to about 1.6 KHz
    • 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
    • Configurable push-pull or open-drain output
    • Output enable pin to quickly disable all the outputs
    We wrapped up this lovely chip into a breakout board with a couple nice extras
    • Terminal block for power input (or you can use the 0.1" breakouts on the side)
    • Reverse polarity protection on the terminal block input
    • Green power-good LED
    • 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
    • "Chain-able" design
    • A spot to place a big capacitor on the V+ line (in case you need it)
    • 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
    • Solder jumpers for the 6 address select pins
    This product comes with a fully tested and assembled breakout as well as 4 pieces of 3x4 male straight header (for servo/LED plugs), a 2-pin terminal block (for power) and a piece of 6-pin 0.1" header (to plug into a breadboard). A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do.

  • 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

  • RasWIK - Raspberry Pi Wireless Inventors Kit (CIS-S005)

    Product description

    The Wireless Inventors Kit for the Raspberry Pi (RasWIK) is an exciting and affordable addition to the Raspberry Pi.  RasWIK demonstrates that with our leading edge technology anyone (and we mean anyone) can build wireless sensors and actuators , you do not need huge experience, a degree or even any tools. We show you even how to connect the devices you build to “the Internet of Things” (IoT) service providers such as Xively. 

    Getting started is just 5 simple steps:

    • 1. Insert the preconfigured SD card to your Pi
    • 2. Plug in the Slice of Radio to the GPIO connector
    • 3. Turn on the Pi
    • 4. Power the XinoRF development board
    • 5. Launch the Python based example application on your Pi
    • That's it!........you are now past step one of your journey to wireless nirvana :)

    You can build wireless devices in just a matter of minutes.  All the code is fully Open Source, you can use, modify and even sell your own products based on this kit. 

    There are 29 fully documented projects. The 17 hardware projects take you from very basic sensors, actuators and light controls to more complicated ones that include measuring temperature and light levels. The 12 fully completed software projects show you how to do more sophisticated stuff, including posting your measurements on the Internet. 

    Out of the box all the hardware is configured to start you off without you writing a single line of code.  The kit comes complete with an SD card image that has starter software and a fully configured Pi operating system already installed.  The devices you make are even interoperable with our off the shelf wireless devices.

    In a review of RasWIK in the October 2013 issue of Custom PC , Gareth Halfacree (co author of the Raspberry Pi manual) said: "It provides possibly the simplest platform for experimenting with wireless sensor networks I’ve ever seen."

    RasWIK  won an outstanding 5 tux in Linux Format,  saw a 4 page spread in Raspberry Pi geek and has had a number of other reviews. In every review, RasWIK comes out to be an excellent way to learn more about your Pi and wireless sensing.

    The youngest WIKer we know of is just 8 years old! If he can do it, you can too :)

    Here is a 17 minute video of a presentation on RasWIK we gave at the Cambridge Raspberry Jam on 21 September 2013. 

    Features:

    • Starter examples require no soldering
    • Comes with plug in wires and a solderless breadboard
    • 4Gb SD card image (saves you lots of Pi configuration)

  • Adafruit Pi Cobbler for Raspberry Pi Model B+ etc (COBPLUS)
    The Raspberry Pi B+ has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B accessories by hooking up a downgrade cable, its probably a good time to upgrade your set up and accessorize using all of the Model B+'s 40 pins.

    That's why we now carry the Adafruit Assembled Pi Cobbler Plus - Breakout and Cable for Raspberry Pi B+. It's an add on prototyping Pi Cobbler from Adafruit specifically designed for the B+ that you can break out all those tasty power, GPIO, I2C and SPI pins from the 40-pin header onto a solderless breadboard. This will make "cobbling together" prototypes with the Pi super easy.

    Designed for use with Raspberry Pi Model B+ only! No soldering required!

    This Cobbler is in a compact shape, which is the least bulky way to wire up. The cable plugs between the Pi B+ computer and the Cobbler breakout. The Cobbler can plug into any solderless breadboard (or even a prototyping board like the PermaProto). The Cobbler PCB has all the pins labeled nicely so you can go forth and build circuits without keeping a pin-out printout at your desk. We think this will make it more fun to expand the Pi and build custom circuitry with it.

    Please note, this product only contains an assembled Cobbler Plus and 40-pin ribbon cable (in slimming Adafruit Black). Raspberry Pi B+, solderless breadboard, breadboarding wires, cables, components, power supply, etc are not included! We do stock many of those items in the shop, so check those out as well!

  • 5" TFT Screen HDMI No Touchscreen 800x480 - For Raspberry Pi (ADA-5TFT)
    Yes, this is a cute little 5" TFT display with WVGA 800x480 resolution. We tried to get the smallest display that would be good for embedded computing usage and at a good price. The visible display measures 5" diagonal and is a 'raw' TTL display as is used in portable electronics. We include a driver board with HDMI, VGA and Composite inputs. The display is very easy to use - simply connect a 5-12V DC adapter to the 2.1mm centre-positive DC jack, then connect a digital video source to one of the ports. Voila, a display!

    It is not an IPS display so its best for direct viewing, our 7" and 10" HDMI IPS displays are designed for any angle view.

    There's a little wired PCB with little buttons that let you enter a menu system for adjusting brightness, color and contrast. It tries to auto-detect which input you have and switches to that one or you can 'select' from the menu keypad which to display.

    To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any device with HDMI, VGA or NTSC/PAL output. It will not work with a device that only outputs DVI (without a DVI->HDMI converter) or SECAM.

    For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to 800x480 in case it doesn't detect the resolution properly. You can see our suggested config.txt in the Technical details tab. The easiest way to edit the config.txt is to put the Pi SD card into an every day computer and edit config.txt with any text editor and save. For use with a BeagleBone black, we found it works when plugged in, no configuration required.

    The Wire Stand is not  included! but is available from here

    A power adapter is not included! Any 5 to 12VDC adapter will work nicely: we suggest our 9V DC adaptor

    Technical Details

    • Power with 5-12VDC
    • Resolution: 800 x 480
    • Visible area: 108mm x 65mm 16:10
    • Brightness: 200cd/m2
    • Contrast: 300:1
    • We ship with a an KD050G21-40N display, or equivalent
    • Display dimensions: 121mm x 76 x 3.1 mm
    • Not HDCP compatible - it cannot be used with 'secured' HDMI sources

  • 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.

  • Pi-Lite - Lots of LEDs for the Raspberry Pi (PiLite Red) (CIS-B040)

    Product description

    The Pi Lite is a large LED matrix display for scrolling text and graphics. It's an exciting way to get a Raspberry Pi to do something physical and fun. It's an easy plug in add on, so no soldering or special skills are required.

    The Pi Lite mixes the highly popular Arduino "Lots of LED's" shield by Jimmy Rogers with the world of the Raspberry Pi. Using standard serial communications (@9600bps), it's really simple to send text and graphics to the 126 LED's. The matrix is powered from an ATMega328p processor which means all the processing of driving the 126 LED's is off loaded from the Pi's processor. This frees the Pi's processor and GPIO for other functions.

    • Fun and practical (perhaps display your emails or tweets in real time, scroll messages that can be seen at a distance)
    • Open source firmware (you can build in extra functions if you desire)
    • Multi function - Scroll text, bargraph, VU meter & graphics (all easy to use by sending just simple text strings)
    • Based on the Jimmy Rogers LOL shield (well tried, tested and supported)
    • 14 x 9 matrix of LEDs (for text or graphics)
    • It's serial so can be used with any TTL micro, radio (eg XRF) or PC interface (for example the popular FTDI cable)
    If you are not yet convinced, we have a Pi-Lite emulator (written in Python), so you can try before you buy.

    Features:

    • On board ATMega328p
    • High quality gold plated PCB
    • 126 Red LEDS (a White version is also available)
    • Data is driven by the Pi serial UART (you may need to setup your serial port, see below docs).
    • Runs at 5 volts off the Pi supply (49ma max)
    • Preloaded software, can be used out of the box to display the following
      • Scrolling Text (speed variable)
      • Bar Graph (vertical 14 bars)
      • VU Meter (horizontal 2 bars)
      • Frame buffer (for graphics and animation)
      • Individual Pixels (turn them on, off or toggle)
    • Pre-built / Plug and Code
    • Ability to install 6 pin ISP or 6 pin FTDI Headers to the ATMega328P for firmware upgrades or your own sketches
    • ATMega328p analog pins are broken onto standard holes (just like the Jimmy Roger shield)
    • I2C from the ATMega328p is available on pins A4 and A5 for daisy chaining of Pi-Lite to create a bigger display
    • Made in the UK
