ESP8266 ESP12E -NODEMCU – CH340

NodeMCU is an open-source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term NodeMCU by default refers to the firmware rather than the development kits. The firmware uses the Lua scripting language. It is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266.
It has a Built-in on-board USB-TTL serial converter based on CH340G, with a Micro-USB socket. Power in for DC 4~9V DC to pin VIN. It has Arduino-like hardware I/O and can program in Arduino IDE.
