WeMos D1 ESP Wroom 02 Board ESP8266 Mini WiFi Nodemcu Module 18650 Battery

This is  WeMos D1 Esp Wroom 02 Board ESP8266 Mini-WiFi Nodemcu Module 18650 Battery. This development board integrates the ESP8266 18650 battery. It operates with a Sony 3000mah 18650 battery that can run for 17 hours. In some cases when we need to add some ESP8266 items you want to be hate to feature power to power. This miniature board can solve this problem.

With nodeMCU,18650 charging system integration and Indication LEDs (green means full and red means Charging) Charge and work are often done easily at an equivalent time. Meanwhile, this design concept rises from the open-source project NodeMCU. This development board integrates 18650 charging and discharging systems with charging and discharging protection. At the same time, an OLED and five directional buttons are integrated to facilitate the development.

Notes:

• This product doesn’t contain a 18650 battery. If the battery is placed in the wrong direction, the charging chip is destroyed.
• Please don’t burn the program during charging. Once you burn the program, please unplug the battery and verify the switch is in the ON position.
