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

optional 3x6x2.5mm switches for reset/prog

SMT 2.56 male header (ebay) used to make board small to fit nicer on breadboard

Future improvements? Extend the board by one pin at each end, relocate GPIO0 to under the antenna section to make 34, 35, 19, 22, 21 accessible
