The compact PCB (95mm x 70mm) of 4 Channel Motor Driver makes it a perfect solution for motor control. The 4 outputs are suitable for interrupt generation and high resolution speed control. The mixing circuit takes 8 inputs of 4 quadrature encoders and generates 4 outputs. Built in control logic allows each motor to be controlled by 2 pins. One pin for speed and one for direction. Low resistance FET H-bridges ensure high efficiency and good motor torque. Each channel is rated for 4A of stall current and each channel has it's own current monitoring circuit.
This motor driver is specifically designed for the Rover 5 chassis the board includes a quadrature encoder mixing circuit for use with up to 4 quadrature encoders. The mixing circuit takes the 2 inputs from a quadrature encoder and mixes them into a single output. The interrupt output changes state when either input changes.
The PCB has two power connectors. One is +5V for logic (Vcc) and one for the motor power supply. The motor power supply should not be connected without first connecting the +5V for logic. This board is rated for a maximum motor supply voltage of 12V. Exceeding this voltage may permanently damage the board.
