  • Zero Point Analog Output for Raspberry Pi (ZeroPoint) (ZPOINT)

    Zero Point Analog Output for Raspberry Pi

    Fully Assembled - No Soldering Required

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


    ZeroPoint is an analog gauge with a prototyping area for your own sensors

    The gauge is a small stepper motor (X27.168) that is driven using an H-bridge (it’s a bipolar stepper so needs to be driven both ways)

    Although it is a standard stepper motor to operate, it only travels through just over 300 degrees before hitting the physical end stops.

    This gauge is used in many vehicles for speedometer, tachometer, etc.

    Using the Python library provided you can set the dial to any position between 0 and 600 which covers 300 degrees around the dial. Use this to show off your sensor readings, CPU usage, number of tweets or whatever you like.

  • 4tronix PicoCon Motor Robot Controller for Raspberry Pi - KIT (PICOCON2)

    PicoCon - "No-Frills" Motor Controller Kit for Raspberry Pi

    Really simple to solder, only 8 components to be soldered

    PicoCon is a basic motor controller for your Raspberry Pi based mobile robot

    This board uses a dual H-Bridge chip controlled directly from the GPIO pins on your Raspberry Pi

    1. Dual H-Bridge driver to drive 2 DC motors (or 2 sets of 2 if using paired motors on each side of the robot)
    2. A 6-pin I2C breakout header is included with 5V, 3.3V and Gnd connections - you can use this to plug in our IP Display module so you know what IP address your wireless robot has been allocated
    3. 2-pin screw terminals used for motor connection and motor power connection
    4. A 10-way female header breaking out many other GPIO pins for you to use in your robot
    5. Directly supported in ScratchGPIO4 onwards using the same addon board definition as PiRoCon "piroconB" - many thanks to Simon Walters for some excellent work
    6. The standard 4tronix python libraries will all work as they all use the same pins  to control the motors

    Motor A: Physical GPIO connector pins 19 and 21 (MOSI and MISO)

    Motor B: Physical GPIO connector pins 24 and 26 (CE0 and CE1)

    You must power the Hall effect sensors separately with 5V to the V and G inputs, the output is taken from the S1 and S2 signals

    The wires from the motor are coloured as follows
    • Black - Motor Ground
    • Red - Motor Power (7 - 12V)
    • White - Sensor Power (5V)
