The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.

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, aiming to provide an access network for embedded products.

The NodeMCU-32S is the core development board based on the 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 more straightforward setup and breadboard use. Using a breadboard for development can simplify the use of this module by using both sides of the standard pin.
