NodeMCU is an open-source firmware and development board that helps you to prototype your IoT product with a few Lua script lines. The development board is based on the ESP8266 WiFi chip with 10 GPIO and 1 ADC input. Each GPIO can be used as PWM, I2C, SPI and 1-Wire. Via the micro USB you can program NodeMCU.
The advanced API for hardware IO uses interactive Lua script which is like Arduino code. The event-driven API for network applications faciliates developers writing code in Nodejs style. It speeds up your IOT application developing process.
The use of FCC & CE certified ESP-12 version of ESP8266 with PCB antenna makes NodeMCU one of the best platforms for IoT application development at the lowest cost.
Finally, programable WiFi module.
Arduino-like (software defined) hardware IO.
Can be programmed with the simple and powerful Lua programming language or Arduino IDE.
USB-TTL included, plug & play.
10 GPIOs D0-D10, PWM functionality, IIC and SPI communication, 1-Wire and ADC A0 etc. all in one board.
Wifi networking (can be used as access point and/or station, host a web server), connect to internet to fetch or upload data.
