+ | - You will be doing a 2-layer daughterboard. Therefore your power must be routed in the signal layers. Pay attention that you try to keep the power routing to the digital and analog parts separate except where they join at the connections to a ground pin from the bronze board header. | ||
+ | - Keep sensitive electrical nodes far away from the noisy digital servo control. | ||
