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.
High performance-price ratio;
Small volume,easily embeded to other products;
Strong function with support LWIP protocol,Freertos;
Suppporting three modes: AP, STA, and AP+STA;
Supporting Lua program, easily to develop.
