The DFRduino M0 is the only Arduino board that supports 5V standard logic levels and uses an ARM Cortex-M0 core. It utilizes a high-performance 32-bit Nuvoton microcontroller as its processing core, with an integrated ARM Cortex-M0 architecture. The board has one USB port, two hardware serial ports, 31 digital pins (partially multiplexed), and 6 analog pins. It expands with an IIS interface, supporting playback and recording of WAV files for a professional Hi-Fi audio experience. The DFRduino M0 is different from the official Arduino M0, requiring a separate IDE board and supports Windows, Linux, and macOS platforms, with version 1.6.0 and above by default.

Furthermore, the DFRduino M0 expands with an IIS interface, supporting playback and recording of WAV files. Combined with a high-end IIS chip, it can provide a professional Hi-Fi audio experience. Note: The DFRduino M0 is different from the official Arduino M0, using a different chip solution. It requires a separate IDE board (see product documentation). It supports Windows, Linux, and macOS platforms, with version 1.6.0 and above by default. For other IDE versions, you can make some modifications according to the FAQ.
