I’m using separate battery packs to provide servo power and control-board power with the micro serial servo controller. I’m trying to figure out if I need one switch or two.
If the control board power is disconnected, are the servos drawing any current at all? I’m told that ordnarily servos draw a couple mA when not receiving any control pulses. But maybe the MSSC board does something clever to disconnect them completely when the board is powered down? Or do I really need two switches?
