Total Price:
$5.65
Untested
$5.65 for 3 boards
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
copper bottom:
copper top:
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
