4 Channel Controller

Each channel is rated for 4.5A of stall current and each channel has it's own current monitoring circuit. Low resistance FET "H" bridges ensure high efficiency and good motor torque. Built in control logic allows each motor to be controlled by 2 pins. One pin for speed and one for direction. As it is specifically designed for the Rover 5 chassis the PCB includes a quadrature encoder mixing circuit. The mixing circuit takes the 8 inputs of the 4 quadrature encoders and generates 4 outputs. These outputs are suitable for interrupt generation and high resolution speed control. This compact PCB is just 95mm x 70mm (3.75inch x 2.75inch) and is a perfect companion for the Spider robot controller. Each unit comes pre-assembled and tested. Supplied in an anti-static bag with additional mounting post to suit Rover 5 chassis's.
