I need a PCB where the center is an ESP32. There's 2 motors connected via CAN (3.3v, tx, rx, ground, on 2.54mm spacing female), an external servo driver board, which needs ground, tx, rx (all female header pins). The battery connects to a 14.8 power bus on the PCB. From this 14.8 power bus, we connect to a small buck converter (3.3V, power and ground from PCB 14.8V) (external, not on PCB), which in then powers the ESP 32. The 14.8 power bus also powers another external, not on the pcb, buck converter which returns back 12.2 V to a new power bus, which just needs to receive up to 20amps via female. From this power bus, we power the servo driver as well ( via 2 male headers, gnd and 12.2v, on the PCB)
