  • 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

  • Bit:Bot Robot for BBC Micro:Bit (BitBot for MicroBit) (BITBOT)
    Bit:Bot Fully Integrated Robot for the BBC Micro:Bit

    NB. BBC Micro:Bit is NOT included unless specifically selected with the checkbox

    This (almost) ready-assembled robot requires no soldering, no wires and nothing more than a screwdriver to complete it.

    The Bit:Bot fully engages children and adults alike, allowing you to explore and code the BBC Micro:Bit using any of the languages available (not all features are supported in all languages)

    Learn here how to control the Bit:Bot with your Bluetooth phone

    Check out these features:
    • 2 micro-metal gear motors. Both fully controllable in software, for both speed (0 to 100%) and direction (forward or reverse)
    • Wheels with rubber tyres for maximum grip
    • Really smooth metal ball front caster
    • 12 mini neopixels in 2 sets of 6 along the arms either side. Select any colour for any pixel, produce stunning lighting effects as your Bit:Bot moves around
    • 2 digital line following sensors. Code your own line-following robots and race them to see whose code produces the fastest lap time!
    • 2 analog light sensors (front left and front right) so your Bit:Bot can be programmed to follow a light source such as a torch, or you could code it to go and hide in the darkest place it can find
    • Buzzer, so you can make beeping sounds whenever you want
    • Powered from integrated 3xAA battery holder with on/off switch and blue indicator LED
    • Easily plug your BBC micro:bit in and out using the edge connector
    • Extension port for addition neopixels (such as McRoboFace)
    • Expansion connections at the front for additional sensors (Ultrasonic rangefinder available now, more in development)
    Optionally, you can add an Ultrasonic Distance Sensor (rangefinder) module. The sensor can be either soldered to the module, or connected via a socket. No soldering is required for either version. The socketed version makes it easier to connect a micro-USB lead to the Micro:Bit, but the soldered version is more robust.

  • Bit:2:Pi BBC Micro:Bit adaptor for Raspberry Pi Addons (Bit2Pi) (BIT2PI)
    Bit:2:Pi Allows the BBC Micro:Bit to Connect to Raspberry Pi Addon Boards

    NB. BBC Micro:Bit and Unicorn pHat are NOT included

    The Bit:2:Pi enables you to re-use all those hundreds of Raspberry Pi addon boards and HATs.

    Simply plug your Micro:Bit into the edge connector and the required Raspberry Pi Hat onto the GPIO connector, then program your Micro:Bit to control the new board. Most Raspberry Pi boards are very simple to program as they are controlled by simple on/off signals on the GPIO connector which are easily copied in the Micro:Bit. We have also used Neopixel hats (eg. Unicorn from Pimoroni) with great success and are happily communicating via I2C as well.

    Selecting which Micro:Bit pin is connected to which GPIO pin, is via a set of configurable jumpers. There is a default set of connections that works for the most common boards, including I2C and SPI connections, but it is a simple matter to unplug a jumper or two, and replace it with a longer wire jumper (4 included) to connect your preferred pins.

    Of course, the original code for the Raspberry Pi won't run directly on the micro:bit but with support from our community we will get more and more boards working and with example microbit code.

    Current boards tested are:
    4tronix: PlayHat, Picon Zero, PiStop, motor controllers
    Pimoroni: Pibrella, Unicorn pHat/HAT. Explorer, Enviro pHat, Blinkt, Scroll pHat

    This board is supplied in two versions, both fully soldered:
    1. Without battery holder
    2. Including 3xAA battery holder so you can run your Raspberry Pi addons without wires!

    Power is supplied to the board and the micro:bit via the micro-USB connector on the side, but there is also an option to add a battery holder to allow completely wire-free operation.

  • Ultrasonic Distance Sensor for Bit:Bot (BitBot) (BITSON)
    Ultrasonic Distance Sensor for Bit:Bot

    NB. Bit:Bot not included

    Ready-Soldered, just attach to your Bit:Bot with the screws provided and off you go.

    Use Microsoft PXT (or MicroPython with some awkward code) to read the distance to an obstacle, then program your Bit:Bot to avoid it.

    Both Ping and Echo signals are on the same pin (Pin 15)

    This accessory is available in 2 flavours:
    1. With the ultrasonic sensor soldered directly to the PCB
    2. With a socket soldered on the PCB that you can plug the sensor into
    The sensor soldered into the PCB is much more robust and reliable, but has a big drawback in that you cannot access the micro-USB connector on the micro:bit unless you either remove the micro:bit or use a right-angled USB lead

    The socketed version allows most USB leads to access the micro:bit, but it isn't as robust.

  • Robo:Bit Robotics controller for the BBC Micro:Bit (RoboBit) (ROBOBIT)
    Robo:Bit Robotics Controller for the BBC Micro:Bit

    NB. BBC Micro:Bit is NOT included unless specifically selected with the checkbox

    This ready-assembled robotics controller board is ready to accept your BBC Micro:Bit, battery power (3 or 4 cells of AA is ideal) and motors of your choice to make your own DIY robot. Use a small box, ice-cream carton or similar to house everything and you can build a really affordable robot for your school, coding club or home.

    Robo:Bit has been cleverly designed so that with a few hexagonal pillars and screws, you can fit the motors, battery box, front casters, line following sensors and even ultrasonic distance sensors and have a very neat and simple robot!

    Robo:Bit uses the ever popular DRV8833 motor driver which allows you to use most small motors that operate in the 3-6V range.

    Connections are provided for lots of the BBC Micro:Bit pins, and all have immediate 3-pin access to power (3.3V) and ground. There are three separate pins for 5V if you need the extra voltage (but don't feed back 5V to the micro:bit as it won't like it!). This is the GVS (Ground, Volts, Signal) system for sensors and servos etc.

    On the left side of the board (the "front" of the robot) is a set of 4 offset holes into which you can simply poke an HC-SR04 ultrasonic distance sensor. The offset holes and gold plating ensure a good connection, but you can also solder it in permanently for added robustness.

    More details in our blog

    In addition to the Robo:Bit board itself, we offer the following options:
    • Fixings pack. Screws, hexagonal pillars and a Pololu caster. This allows you to fit standard yellow motors (not included) and immediately get a robot working
    • Line follower pack. Includes 2 line follower modules, hexagonal pillars, screws and short 10cm GVS leads

    Gizmos
    Many Gizmos are already available and more are on the way. Each Gizmo connects directly to the Playground with usually one connection cable (Traffic Lights uses 3 cables, one for each colour). As with our Crumbs, the Gizmos are colour coded:
    • Blue - Digital Input (eg. Button)
    • Yellow - Analog Input (eg. Dial)
    • Black - Digital Output (eg. Buzzer)
    • Red - Analog Output (eg. motors)
    • White - Smart pixels ("Sparkles")

    Playground for BBC micro:bit

    This is an exciting new way to use your BBC micro:bit, without requiring crocodile clips which can be difficult for small people to use.

    Also, this new approach allows the use of a single cable for most addons, instead of 3 crocodile clips

    See our blog for detailed usage and programming information

    Features:
    • Fittings for your micro:bit (micro:bit not included, unless selected)
    • Battery holder for 2xAA batteries permanently fitted (batteries not included)
    • Sturdy On/Off switch
    • Blue power indicator LED
    • White LEDs on all 3 inputs to show when active
    • The three Pins (Pin 0, Pin 1 and Pin 2) from the micro:bit are each brought to a new 3-pin connector as well as to a crocodile clip compatible terminal, so you can still use crocodile clips for your existing addons
    • Each new connector includes the signal as well as power and ground
    • Fast and easy to connect

    Optional Extras:
    • BBC micro:bit with USB cable
    • 20cm connection cables
