ESP32 Forum

I just purchased an ESP32 development board with OLED, Bluetooth and Wifi.
I would like to use this as a GPS logger for my RC cars so it would need to run on battery power

I noticed the board has a connector for a 3.7V battery.

Does anyone know where these batteries can be purchased?

Thanks

Unless your board includes charging equipment, it is probably dangerous to use the battery connector. 3.7V lipo batteries can be easily found on almost any online marketplace- amazon, aliexpress, gearbest, banggood.
