Hello, I'm using the adafruit motor shield with Udoo. I'm controlling three motors which in the worst-case (when all are blocked) need a total current of roughly 2 A. The shield can be configured to power the motor from an external power supply or from the VIN pin. According to the Udoo schematics the PSU is directly connected to VIN (more or less, there are some filters). Is it safe to take 2 A out of VIN (provided the PSU is sufficient, of course)?
