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 ESP32projects you must add a power bank to provide the power. This tiny board could solve such problems. A LG 3000mAH 18650 battery (NOT include) could make ESP32 run 17 hours or more.
18650 charging system integrated.
