ESP32-S2 WEMOS S2 Mini Development Board

The S2 Mini is a powerful, compact development board designed for high-performance IoT projects. Built on the ESP32-S2 single-core processor, it serves as a significant upgrade to the classic WEMOS D1 Mini. It maintains a similar small footprint but nearly doubles the available GPIO pins and adds advanced features like native USB OTG and 2MB of PSRAM for memory-intensive applications.

Key Features

• 
  

  Powerful Processing: Running at 240MHz, the ESP32-S2 provides ample speed for complex computations and real-time tasks.

  
  


• 
  

  Enhanced Memory: Includes 4MB Flash for your code and 2MB PSRAM, which is essential for projects involving image processing, large data buffers, or complex web servers.

  
  


• 
  

  Native USB Type-C: Features a modern Type-C connector for power and programming. The ESP32-S2 has an internal USB-to-Serial converter, simplifying the hardware design.

  
  


• 
  

  High I/O Count: Despite its "Mini" size, it offers 27 GPIO pins, providing massive flexibility for sensors, displays, and actuators.

  
  


• 
  

  Shield Compatibility: Designed to be compatible with most LOLIN D1 Mini shields, allowing you to use existing expansion boards for relay control, environmental sensing, and more.
