ESP8266 WIFI Module with 18650 Battery Holder Box Kit ESP-WROOM-02 Development Board D1 MINI WIFI Modules CP2102 USB Micro

Call it a "WiFi battery." I want to make it easier to develop the ESP8266 ESP8266 project by adding 18650 battery.

When you do some ESP8266 projects you must hate to add power supply. This micro-board can solve such problems. The 3000mah 18650 battery will keep the ESP8266 running for 17 hours or more.

What makes it special?

· Compatible with nodemcu.

· 18650 charging system integration.

· Indicator LED (green means full red means · charging) can be used while charging.

· Switch control power supply.

· SMT connector for sleep mode · 1 Additional LED programmable (gpio16)

· 0.5a charging current

· 1A Output

· Overcharge protection

· Over-discharge protection

· 10 digital pin read/write/interrupt/PWM/I2C/line support (except D0)

· Be careful with analog inputs + -.

If the battery is oriented the wrong way, the charging chip will be damaged.
