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 breadboard compatible.
- Optimized for ultra low power and ease of use.
- One of the smallest devboard for ESP8266.
- Measure battery voltage through voltage divider with zero poweruse when not measuring.
