Wemos esp-wroom-02 Pocket 8266 D1 mini WIFI Module --ESP8266+18650 Battery


Detailed description:


This develop board integrated ESP8266 and 18650 battery. A standard LG 3000mAH 18650 battery could run it 17 hours.

What is it?

You can call it "WiFi Battery". I added a 18650 battery to ESP8266 make ESP8266 more easy to develop projects.


Why did you make it?

When you do some ESP8266 projects you must hate to add a power bank to provide the power. This tiny board could solve such problems. A LG 3000mAH 18650 battery could make ESP8266 run 17 hours or more.


What makes it special?

· Same with NodeMCU.


· 18650 charging system integrated.


· indicate LED inside(Green means full& Red means charging)


· Charging and working could be at the same time.


· 1 Switch could control the power.


· 1 SMT connector could be used to sleep mode


· 1 extra LED could be programmed(Connected with GPIO16[D0])


· 0.5A charging current


· 1A output


· Over charge protection


· Over discharge protection


· 10 digital pins write/read/interrupt/pwm/I2C/one-wire supported(except D0)


· 1 analog input


Be careful + and -. If you put the wrong direction of battery the charging chip will be destroyed.
