4 channel motor cotroller with encoder mixing circuit
This is the 4 channel motor controller from DAGU. Although designed for the Rover 5 chassis this controller is suitable for any small robot using Omni or Mecanum wheels.
4x low resistance FET "H" bridge rated for 4.5A stall current each.
4x Current sensing circuit with an output of aproximately 1V per amp of current draw.
4x Quadrature encoder mixing circuit.
The built in mixing circuitry mixes the 2 inputs from the quadrature encoder into a single output of twice the frequency. This allows a single interrupt pin to monitor both outputs of a quadrature encoder. Speed and distance can also be measured with twice the resolution compared to monitoring a single output. See the attached instruction manual for more details.
