Wemos Wi-Fi and Bluetooth Battery ESP32 Development Board With 18650 Lithium Battery Shield

This is Wemos Wi-Fi 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 Wemos Wi-Fi and Bluetooth Battery ESP32 Development Board With 18650 Lithium Battery Shield.
