Please note our offices are closed for Chinese New Year from the 15th through the 21st of February. Orders can still be placed, but will not be processed until the 22nd. Thank you for understanding, and until then, Happy New Year!


I know you love Arduino and the Arduino IDE, but I still want to introduce this small but powerful NodeMCU-32S board to you. Spend only 5 minutes to install the ESP32 Arduino core and USB drivers and then you're good to go! Check out the starter tutorial here.

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 WiFi SoC 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.

The NodeMCU-32S is the core development board based on ESP-32S module. The development board continues the classic NodeMCU 1.0 design, with the  I / O pins placed on either side of the board. This allows for easier setup and breadboard use. Using a breadboard for development can simplify the use of this module by making use of both sides of the standard pin.


Open source, interactive, programmable, simple & intelligent, plus containing WIFI + Bluetooth hardware. In other words, it's a powerful little board to keep in your toolkit.

  • Powerful operating hardware IO as Arduino
  • Using Nodejs similar syntax to write network applications
  • Ultra-low-cost WIFI module
  • Dimension: 25.6x 48.1mm
