Description

ESP8266 ESP-12 minimal stabilized circuit schematic and PCB

With breadboard friendly headers and Wemos D1 mini pin numbers

Designed for battery operation:

Voltage regulator: Torex XC6220B331PR-G (8uA quiescent current, 1000mA max)

VIN: max. 6V

To enable self-wake from deep sleep, solder a 0 Ohm resistor over the WAKE pads

You can use a 0 Ohm instead of a 470 Ohm resistor on TX, or solder a bridge.

The VIN diode can also be replaced by a 0805 0 Ohm resistor
