NodeMCU Lua V3 ESP8266 WIFI with CH340C
This is the famous NodeMCU which is based on ESP8266 WiFi SoC. This is version 3 and it is based on ESP-12E (An ESP8266 based WiFi module). NodeMCU is also an open-source firmware and development kit that helps you to prototype your IoT(Internet of Things) product within a few LUA script lines, and of course you can always program it with Arduino IDE.
Features:
Open-source
Interactive
Programmable
Low cost
Simple
Smart
WiFi enabled
Arduino-like hardware IO
Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware
Code like Arduino, 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
Lowest cost WiFi
Less than $2 WiFi MCU ESP8266 integrated and esay to prototyping development kit
We provide the best platform for IoT application development at the lowest cost
