RP2040 + ESP32-C3 Dual-MCU Board – WiFi, Bluetooth & Dual-Core

The RP2040 + ESP32-C3 Dual-MCU Board is a high-performance development platform that combines the best of Raspberry Pi’s silicon with Espressif’s wireless expertise. This unique board integrates two independent processors, offering developers unprecedented flexibility to partition tasks between a high-speed dual-core controller and a dedicated wireless communication engine.

Intelligent Dual-Core & Wireless Integration

The board features the RP2040 with its dual-core ARM Cortex-M0+ for heavy-duty processing and the ESP32-C3 for robust Wi-Fi 802.11 and Bluetooth 4.2+BLE connectivity. Both MCUs can operate standalone, or they can communicate via an internal UART serial link. This architecture allows you to offload networking stacks to the ESP32-C3, freeing up the RP2040 to handle real-time sensing, motor control, or display processing without interruption.

Designed for Seamless Development

Equipped with a specialized onboard USB switch, this board allows you to toggle the USB connection between the RP2040 and the ESP32-C3 for easy programming and debugging of either chip. With dedicated user LEDs and buttons for each MCU, you have full tactile and visual control over both processors, making it a perfect environment for complex IoT prototyping and embedded system design.
