Thanks for the quick response,
I think it would be better to have the servos on a separate power rail to avoid breaking the board (since theoretically, if all 12 servos are under load they could reach up to 36 amps)
I’m not quite sure how TX and RX signals work but I assume they are independent from the power source. In that case, could you tell me if the following schematic will work with this board? The small blue rectangle represents a servo connector, and I’ll probably extend the same grid using channels 0-11 for all 12 servos.
I don’t really know how the GND on boards work so I assume there is no danger to connect the power rail GND to the board through a pin?
Thanks again!
