I've a PCB with quite some electronics including a few motor drivers (30V, 100kHz PWM), and a few brushed DC motors 1 meter further away. These motors each have a quadrature encoder, so next to their 2 motor leads, they also require wiring for a 5V supply and have 2 channel outputs (wrt the ground of the 5V supply).
Without going in details why, I cannot use one long bundle of cables to directly connect the PCB to the motor.
Instead I need to use a long, small PCB in between to interconnect the main PCB and the motor.
_________ | main | _________________________ _________ PCB |_________| long, small PCB |__________| motor | | wires |_______________________| wires |_______| | ________|
Normally I would twist the motor leads, but how to implement wire twisting on a PCB?
