NodeMCU is an open source IoT platformIt uses the Lua scripting language. The platform is based on the eLua open source project "NodeMCU-32S" is based on the ESP-32S module. The platform uses many open source projects such as lua-cjson, spiffs "NodeMCU-32S" includes firmware that can run on ESP32 Wi-Fi SoC chip, and hardware based on ESP-32S moduleESP32 is a WiFi+ chip developed by Espressif in Shanghai. It is designed to provide access network functionality for embedded products "NodeMCU-32S" is a core development board that is designed by Emerson based on the ESP-32S module. The development board continues the classic design of the NodeMCU 1.0, bringing out most of the I/O pins on both sides, allowing developers to connect peripherals according to their needs. When using breadboard for development and debugging, the standard pin headers on both sides makes the operation easier and more convenient.
