Wemqs WiFi and Bluetooth Battery ESP32 Development Board With 18650 Lithium Battery Shiel

This is Wemqs WiFi and Bluetooth Battery ESP32 Development Board With 18650 Lithium Battery Shield. ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution takes up the least amount of printed circuit board area. This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology, power and RF properties best, which is safe, reliable, and scalable to a variety of applications. When you do some ESP32 projects you must add a power bank to provide the power. This tiny board could solve such problems. An LG 3000mAH 18650 battery (NOT include) could make ESP32 run 17 hours or more. Features: High performance-price ratio Small volume, easily embedded to other products Strong function with support LWIP protocol, Freertos Supporting three modes: AP, STA, and AP+STA Supporting Lua program, easily to develop 18650 charging system integrated. Ultra-low power consumption Indicate LED inside(Green means full& Red means charging) Charging and working could be at the same time. 1 Switch could control the power. 1 extra LED could be programmed(Connected with GPIO16[D0]) 0.5A charging current 1A output Overcharge protection Over-discharge protection Full ESP32 pins break out Package Includes: 1 x ESP32 Development Board With 18650 Lithium Battery Shield
