ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and tool management module.
The entire answer takes up the least amount of printed circuit board house.
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 absolute best, which is protected, reliable, and scalable to a number of applications.
High performance-value ratio
Small volume, easily embeded to other products
Strong serve as with Reinforce LWIP protocol, Freertos
Supporting three modes: AP, STA, and AP+STA
Supporting Lua program, easily to develop
