Pins EN, 34, 35, 19, 22, 21 are underneath the esp3212 antenna area making them hard to access

Optional voltage regulator on underside of board, XC6203 (ebay) - solder bridge or a zero ohm resistor on the 0805 pad marked with XX for no regulator

100nF 0805 cap, 5x 10k 0805 resistors for pullups/downs can all be left off if not needed
