WI-FI enabled: for -like hardware IO, Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware. Code like for , but interactively in Lua script. Nodejs style network API. Greatly your IOT application developing process. 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 , which is safe, reliable, and scalable to a of applications.
