Schematic
Features/BOM
- x1117-3.3 voltage regulator (AMS1117, LM1117,…) - IC1 - [SOT-223]
- Input, output(C1, C2 - Tantalum 10µF [1206]) and decoupling capacitor(C3 - Ceramic 100nF [0805])
- Pullup resistors for CH_PD(R1), RESET(R3) and GPIO0(R4) - 10K [0805] *
- Pulldown resistor for GPIO15(R2 - 10K [0805]) *
- Reset button “tactile” (connects Reset to GND) - [THT]
- Flash button “tactile” (connects GPIO0 to GND) - [THT]
- ESP-12E pin header(bottom pins) **
- Breadboard compatible (one row stays free on both sides)
* R1 and R2 could also be a solderbridge or 0 Ohm resistor if the “pulled” pin will not be used
** The additional bottom header on the ESP-12E can not be used without modifying the ESP module:

Note: The idle current consumption of the 1117 voltage regulator is about ~5mA!
