Homefixer ESP8266 devboard

Description

Another development board for ESP8266-12F. But this one is a bit different, made to be easy to set up without the need for additional hardware like programmers and voltage regulators. A wide voltage range switching regulator enables the user to use different battery technologies from 1 AA cell up to LiPo cells. If you are using LiPo cells there is also a USB charger on the board. The ADC is connected to the battery with a voltage divider that you can turn off when not used to save power.

The board has been made as small as possible but still with a lot of functions and is breadboard compatible.

Features

• Optimized for ultra-low power and ease of use.

• One of the smallest devboards for ESP8266.

• Measure battery voltage through a voltage divider with zero power when not measuring.

• All pins except G15, Reset, and Chip Enable are exposed on the pin header to the user.

• CP2104 USB to UART with auto-reset support for getting into bootload mode before firmware upload.

• LiPo charging from USB.

• Wide range supply voltage to work with many different battery configurations.

• Exposed setting pins for TSP61201.

• Deep sleep prewired, only need to connect with a solder jumper.

• Breadboard compatible.
