Supported Ports

CircuitPython supports a number of microcontroller families. Support quality for each varies depending on the active contributors for each port.

Adafruit sponsored developers are actively contributing to atmel-samd, mimxrt10xx, nordic, raspberrypi, and stm ports. They also maintain the other ports in order to ensure the boards build. Additional testing is limited.
