Product Introduction:
This development board integrates an ESP8266 18650 battery, and a standard 3000mah 18650 battery can run for 17 hours.
It can be called a "WiFi battery". I want to make it easier to develop the ESP8266 ESP8266 project by adding 18650 batteries.
When you do some ESP8266 projects, you must hate adding power to provide power. This micro board can solve such problems. The 3000mah 18650 battery can run the ESP8266 for 17 hours or more.
