18650 Lithium Battery, 0.96 Inch OLED Display, Wi-Fi, Bluetooth ESP32 Shield Module, ESP-32 ESP8266 CP2102, Development Board Module
Product Description
- Supporting Lua program, easily to develop.
- Supporting three modes: AP, STA, and AP+STA.
- Small volume, easily embeded to other products.
- Strong function with support LWIP protocol, Freertos.
- High performance-price ratio.
When you do some ESP32 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 ESP32 run 17 hours or more.
