Wireless module CH340 NodeMcu V3 Lua WIFI Internet of Things development board based ESP8266 ESP8266 CH340 V3/ESP8266 CP2102 2.Interactive 3.Programmable 4.Low cost 5.Simple 6.Smart WI-FI enabled Ard--uino-like hardware IO Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware. Code like ard--uino, but interactively in Lua script. Nodejs style network API Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style. Greatly speed up your IOT application developing process. Introduction: 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. Features: High performance-price ratio Small volume, easily embeded to other products Strong function with support LWIP protocol, Freertos Supporting three modes: AP, STA, and AP+STA Supporting Lua program, easily to develop _x000D_
