From the GitHub release page:

This is CircuitPython 8.2.0-beta.0, a beta release for CircuitPython 8.2.0, and is a new unstable release.

Notable changes to 8.2.0 since 8.1.0

  • Continued enhancement of synthio.
  • RP2040 alarm.sleep_memory.

Download from

Firmware downloads are available from the downloads page on The site makes it easy to select the correct file and language for your board.


To install follow the instructions in the Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.

Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).

Port status

CircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable (but see Known Issues below):

  • atmel-samd: Microchip SAMD21, SAMx5x
  • cxd56: Sony Spresense
  • espressif: Espressif ESP32, ESP32-S2, ESP32-S3, ESP32-C3
  • nrf: Nordic nRF52840, nRF52833
  • raspberrypi: Raspberry Pi RP2040
  • stm: ST STM32F4 chip family

These ports are considered alpha and will have bugs and missing functionality:

  • broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
  • litex: fomu
  • mimxrt10xx: NXP i.MX RT10xxx
  • silabs: Silicon Labs MG24 family
  • stm: ST non-STM32F4 chip families

Known issues

  • ESP32-S3 has issues with I2C devices that sleep (LC709203F), use clock stretching, or violate the I2C protocol (e.g., BNO055). Retry operations on these devices as necessary, or use ESP32-S2 boards.
  • Espressif boards have ESP-IDF storage leaks and occasionally crash after extended WiFi use.
  • See for other issues, including issues still to be addressed for:
