NodeMCU-32S is a core development board designed by Essence based on the ESP32-32S module. The development board continues the classic design of NodeMCU 1.0, leading most of the I/O to the headers on both sides, and developers can connect peripherals according to their needs. It features WiFi+Bluetooth connectivity, onboard CH340, and keys. What's more, all the I/O pins of the ESP32-S module are accessible via the extension headers. When using the breadboard for development and debugging, the standard headers on both sides can make the operation easier and more convenient
Thanks to the rich open-source resources, it supports development in various ways such as Lua/AT commands/MicroPython/Arduino/IOT source code, etc. helping you to fast prototype IoT applications.
