adafruit/circuitpython 9.2.3 on GitHub

This is CircuitPython 9.2.3, the latest bugfix revision of CircuitPython, and is a new stable release.

WARNING for nRF52 boards only: If your board has an nRF52 UF2 bootloader whose version is before 0.6.1, you will not be able to load CircuitPython 8.2.0 and later, due to increased size of the firmware. See these instructions for updating your bootloader.

Highlights of this release

Fix ESP32-S3 regression: did not connect properly to USB without an interposed hub.
New boards: Adafruit Sparkle Motion and Mini Sparkle Motion, M5Stack StampS3.

Incompatibility warnings

Download from circuitpython.org

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

Installation

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

Try code.circuitpython.org or 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-C2, ESP32-C3, ESP32-C6
nordic: Nordic nRF52840, nRF52833
raspberrypi: Raspberry Pi RP2040, RP2350
stm: ST STM32F4 chip family

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

analog: Analog Devices MAX32690
broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
espressif: ESP32-P4
litex: fomu
mimxrt10xx: NXP i.MX RT10xxx
renode: hardware simulator
silabs: Silicon Labs MG24 family
stm: ST non-STM32F4 chip families
