Beetle RP2040 Mini Development Board from

Designed by Raspberry Pi, RP2040 features a dual-core ARM Cortex-M0+ processor with up to 133MHz clock and 264KB internal RAM, and supports USB 1.1 devices, which allows users to focus on function implementation instead of spending too much time and effort on improving codes.

DFRobot Beetle RP2040 is a development board built around the RP2040 chip. It has a compact size of 27mm×20mm, which is easy to be embedded into small devices or projects.


  • RP2040 microcontroller chip designed by Raspberry Pi
  • 2M FLASH storage
  • Small size of 27mm x 20mm
  • Immersion gold pad for easy soldering
  • Support C++, MicroPython, and Arduino C programming
  • 8 GPIO pins, I2C × 1, UART × 2, SPI × 1, digital port × 8, analog port × 2
  • Onboard BLINK_LED light
  • USB TYPE-C interface
  • Work well with USB 1.1 device

The board adopts a beginner-friendly large pad design, effectively reducing the difficulty of soldering. And it provides 8 carefully-selected GPIO ports that can serve as I2C, UART, SPI, digital port, analog port, etc., more convenient and flexible for users to develop various applications.
