Designed originally for 4 wheel drive, this driver PCB is ideal for any small robot using either Omni or Mecanum wheels. Current sensing for each motor allows the processor to determine if a motor has stalled or is under excessive load.
The encoder mixing circuit:
Unlike most motor controllers this PCB includes 4 mixing circuits 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. Note that the interrupt output changes state when
either input changes.
Features include:
- 4x low resistance FET “H” bridges.
- Each channel rated for 4A stall current.
- Easy to use control logic.
- Current monitoring for each channel.
- Quadrature encoder mixing circuitry.
