NODEMCU-ESP8266 Wifi Development Board on CH340g



The NodeMCU V3 is a breadboard-friendly open-source ESP8266 development kit, armed with the CH340G USB-TTL Serial chip. The CH340 line of chips is notoriously known as the affordable alternative to the CP210x. Whilst cheaper, CH340 is super reliable even in industrial applications. It is tested to be stable on all supported platforms as well. With an integrated USB interface, you can easily use it with the Arduino IDE or NodeMCU Lua.

NodeMCU is an IoT Module based on the ESP8266 wifi Module. NodeMCU uses Lua Scripting language and is an open-source Internet of Things (IoT) platform. This module has CH340g USB to TTL IC. It is based on Lua language and provides a high-level API to encapsulate the hardware operation of esp8266. It allows similar to Arduino Hardware interaction makes it easy for software developers to operate hardware devices, at the same time, nodemcu also provides event-driven network API and nodejs style programming Cheng way is to let Internet developers like fish in the water.
