Adafruit have digital IO, analog in\/out, I2C, SPI, PWM working so far and more on the way. For example, the SDIO SD card is not yet supported natively. DisplayIO is also not yet supported.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/github.com\/stm32duino\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eArduino is supported through STM32duino\u003c\/a\u003e.

That said, STM32 support is really good, and we were able to run just about every sketch we tried.\u003c\/li\u003e\n\u003cli\u003eMicroPython support is very solid but Adafruit does not provide MicroPython libraries for sensors!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAdafruit tested this in Arduino STM32duino with all our FeatherWings and only the RFM69\/RFM9x libraries did not work (they are very platform specific).
