2 layer board of 1.23x2.05 inches (31.22x52.17 mm).
Shared on February 24th, 2017 09:02.

For an ESP8266, with programming connectors and switches and supporting Deep Sleep mode. Designed to connect to a BME280 Temp/Humidity/Barometer by wire using I2C.

  • U1 ESP-12F
  • U2 MCP1700T-3302E/TT SOT-23

The board design has been updated since this version:

  • I missed off a pull up resistor on CH_PD (but can easily be tacked on the back of the board if you use this version)
  • redesigned the layout so my fingers could get at the switches ;-)
  • Added a switch to bypass the regulator so the circuit could be used either with 3.2v LifePO4, or 3.7v Li-ion batteries
