RoboHAT - Complete Robotics Controller for Raspberry Pi

Supports all models of Raspberry Pi with 40 pin Connector *

Programming is fully supported in both Python and Scratch GPIO


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.

See blog post here for usage details and code download

* The RoboHAT also fits the 3B+ and 4B models of Pi, but you should use 10mm spacers to keep it away from the POE pins that the nice people at Raspberry Pi added. We now include 10mm spacers with every RoboHat.
