3PCS S3 Expansion Board with Power Supply, GPIO 1-to-2 Expansion 44Pin Breakout Board Compatible with -S3-WROOM-1 N8R8/N16R8 Module -S3-DevKitC-1, with 9V 2A Power Adapter

  • The expansion board is equipped with a DC power connector that supports –9V DC input and features an integrated on-board voltage regulator circuit. When a project requires driving multiple peripherals, the system can be powered directly from an external power supply, providing stable power support.
  • Featuring a standard header connector design, this product is compatible with 44-pin ESP32 S3 development boards, including those equipped with the ESP32-S3-WROOM-1 N8R8/N16R8 module and the ESP32-S3-DevKitC-1. The plug-in design provides easy access to GPIO and power connectors, facilitating prototyping, testing, and electronics project development.
  • The expansion board features separate and 5V power connectors that can supply power to peripheral modules such as sensors and displays, making it easy to connect multiple devices simultaneously. It is suitable for robotics, automation control, embedded systems, and IoT development projects.
  • The 44-pin expansion board features a 1-to-2 GPIO expansion design, providing dual connection points for GPIO signals. Clearly labeled GPIO, power, and ground connections make wiring, peripheral expansion, prototyping, and debugging easier.
  • Expansion boards reduce the complexity of wiring when connecting multiple peripherals, making it easier to add, remove, or adjust connections during the development process, and simplifying project setup, modification, testing, and debugging.
