I'm looking to limit noise from a small circuit I'm building that uses a pair of 1.5-6V motors running via PWM through a ULN2803. I'm unable to completely segregate the motor traces, so I'm trying to belt/suspender what I *can* do (twisting wires, separate 5V line, flyback diode, maybe a ferrite).
I want to use 0.1uF ceramic caps to decouple the motors, and everything I see uses one directly soldered to the motor terminals. Is there any benefit or detriment to solder the caps on the PCB where the motor wires (<5 inches long) plug in?
