The WeMos D1 Esp Wroom 02 Board is a miniature development board that solves the problem of powering ESP8266 items. It integrates an ESP8266 18650 battery, allowing for extended runtime of 17 hours or more with a Sony 3000mAh 18650 battery. The board features a 18650 charging system, indication LEDs (green for full, red for charging), and the ability to charge and work simultaneously.
Important notes: Avoid inserting the 18650 battery in the wrong direction to prevent damage to the charging chip. Do not burn the program while charging. Use a 5V 500mA charging charger for optimal performance.
The board includes one AD input, micro USB input, programmable LED (D0), and an AUTO PROGRAM circuit. It is compatible with Arduino and NodeMCU, offering analog input with built-in dividing resistor. The SOLDER terminal allows for SLEEP MODE functionality.
With overcharge and over-discharge protection, the board ensures safe operation. The integrated OLED and five buttons make development more convenient. The design is inspired by the NodeMCU project, integrating 18650 charging and discharging systems, OLED, and directional buttons.
Package Includes: 1 x WeMos D1 Esp Wroom 02 Board ESP8266 Mini WiFi Nodemcu Module 18650 Battery
