RoboHAT - Complete Robotics Controller for Raspberry Pi

Supports all models of Raspberry Pi with 40 pin Connector: Model A+/B+ as well as Pi 2 and 3 Model B

Programming is fully supported in both Python and Scratch GPIO

This is the replacement for the Pirocon


RoboHAT is a complete robotics controller for your Raspberry Pi based mobile robot. Just look at the features provided in this small board:

  • Fully HAT specification compliant
  • 5V switching regulator to safely power the robot and the Pi from 7V to 10V batteries
  • LED indication of 5V power status
  • High efficiency, dual H-Bridge driver to drive 2 DC motors (or 2 sets of 2 if using paired motors on each side of the robot)
  • 6, 5V level shifted GPIO inputs with GVS 3-pin connectors (Ground, Volts, Signal)
  • 4, 5V level shifted GPIO outputs with GVS 3-pin connectors
  • 4-pin male header to directly plug in an Ultrasonic distance sensor. Only uses a single pin on the Raspberry Pi GPIO
  • Optional separate power for motors (up to 11V and 1.5A per motor)
  • The output connectors can be used directly to drive servos
  • I2C breakout connector (standard 4tronix I2C port)
  • Includes 2 mounting pillars and screws so it can be securely mounted to your Raspberry Pi
  • All of this is directly supported in Scratch GPIO 4 onwards - many thanks to Simon Walters for some excellent work
  • Python library module and examples freely available
This controller board is supplied fully assembled. No soldering is required.
