NodeMCU is an open source IoT platform, it uses Lua scripting language programming, the platform is based on the eLua open source project, the platform uses many open source projects, such as lua-cjson, spiffs. "NodeMCU-32S" includes the ESP32 Wi -Firmware on the Fi SoC chip and hardware based on the ESP-32S module.

Node MCU-32S This development board continues the classic design of NodeMCU 1.0, leading most of the I/O to the pins on both sides, and developers can connect peripherals according to their needs. When using a breadboard for development and debugging, the standard headers on both sides can make the operation easier and more convenient.

Product Features:

1. Contains USB serial port, plug and play

2. 36 GPIOs, each can be configured as PWM, I2C

3. FCC&CE certified WiFi module with built-in antenna
