NodeMCU V2 ESP8266 Development Board
ESP12E DevKit is based on the development of ESP8266 which is an ultra-low-power UART-WiFi module. It’s designed for mobile devices and networking applications, usually it can be applied to the Internet, LAN communications, smart home fields, industrial control, and other handheld devices. ESP12E DevKit selects the on-board PCB antenna package with 2.54 in-line package, so that it can debug equipment or direct product applications conveniently. ESP12E DevKit encapsulates ESP8266 hardware operation API by Lua language, which could enhance the ability of developers to quickly design products.
