Mini Development Board, ESP32-C3 / S3 / RP2040

Build a compact electronics prototype around a development board with a small onboard display. Choose ESP32-C3, ESP32-S3 or RP2040 according to the wireless, USB and software requirements of your project.

• ✅ Show small status information locally - the onboard display gives your project a compact visual output.
• ✅ Choose the processor for the job - three different board versions are listed.
• ✅ Connect through USB-C - the connector provides the board's USB connection for a suitable development setup.

Choose the Board by Its Actual Capabilities

ESP32-C3 and ESP32-S3 versions list 2.4 GHz Wi-Fi and Bluetooth Low Energy; the RP2040 version does not list built-in wireless. The S3 and RP2040 support native USB functions, while the C3 USB connection is described as serial/JTAG rather than a general USB device interface.

Choose the exact board version before developing display code, and use its matching documentation. GPIO allocation, memory and USB functions differ between processors, so the right board definition and pinout are essential.
