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