Dr Simon Monk Raspirobotboard 2

.. or RasPiBot2 as it’ll be know from now on 🙂

This is a robot controller board with usual features of bi-directional motor control, ultrasonic plugin support, 2 inputs, 2 outputs and I2C for expansion.

Its unique feature is that is uses a switched mode power supply which means it can be powered from 6 x AA batteries (I recommend hybrid NiMh myself) and doesn’t need a heat-sink which means it doesn’t waste heat and makes more efficient use of available power 🙂

There are two motor controllers

MotorL and MotorR, 2 Leds (Led1/2), two outputs (Output1/2) two swithc inputs (Switch1/2) and an Ultrasonic sonar port
