CircuitPython has a number of “ports” that are the core implementation for a variety of microcontroller families. Stability varies on a per-port basis. As of this release,
stm for the F4 family are stable.
stm for other STM chip families are being actively improved but may be missing functionality and have bugs.
mimxrt10xx are in an alpha state and will have bugs and missing functionality.

Breaking changes since 5.x
i2cperipheraland the class in it is changed as well.
stopkwarg has been removed from

- The default speed of busio.I2C and board.I2C is now 100khz, not 400khz as before. Use
busio.I2Cto set the speed explicitly. #3471 Thanks @caternuson, @ladyada, @hierophect and @tannewt.
_bleio.ConnectionErrorhas be removed. Code will now raise the native
- ESP32-S2: Crash when repeatedly creating and destroying busio.I2C object on ESP32-S2. #3846.
- Writing several larger files to
CIRCUITPYwhen there is no serial connection to the board can take a long time or hang. To speed up copying, open a serial (REPL) connection. #3986.
