Status: ❌ Not supported in official Arduino ecosystem.
Note: No publicly available Arduino Core, but NuMicro SDK and CMSIS are available. DIY port is possible.
Official Arduino Support: Currently available for the NUC131 series via the NuMaker UNO platform.
Community Support: The huaweiwx/ARDUINO_Nuvoton project offers experimental Arduino core support for the M051 series.
Recommendation: For stable and official Arduino development, consider using the NuMaker UNO platform. If you’re interested in experimenting with the M051/M058 series, the community-driven project may serve as a starting point, keeping in mind potential limitations and the need for further development
