I'm looking at options for controlling multiple Servos I keep finding the same board, the PCA9685
Which is great, I see people using them for those small 9g servos, but what about servos that pull close to an amp or more each? Is such a controller suitable for that?
I've read that the external power supply pins are directly connected to the V+ and ground pins at the bottom for each servo. So if I wanted to, could I just use the PWM signals from this board and connect the servos' supply voltage outside of the board (I don't like the idea of running more than 2-3 amps through those traces!) keeping a common ground?
