Based on the ESP32 board, the NodeMCU-32S is also an open source IoT platform. It uses Lua script and a lot of open source projects, such as lua-cjson, and spiffs. It contains firmware that can run on ESP32 WiFiSoC chips and its hardware is based on ESP-32S modules. The ESP32 is a WiFi + Bluetooth chip developed by Shanghai Espressif, which aims to provide access network for embedded products.
