Documentation

Documentation is available in readthedocs.io.

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:

• atmel-samd: Microchip SAMD21, SAMx5x
• cxd56: Sony Spresense
• espressif: Espressif ESP32-S2
• 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
• espressif: ESP32-S3, ESP32-C3
• litex: fomu
• mimxrt10xx: NXP i.MX RT10xx
• stm: ST non-STM32F4 chip families

Changes since 7.2.0-rc.2

This release is a relabeling of 7.2.0-rc.2 and is otherwise the same as that release.

CircuitPython 7.1.1

This is CircuitPython 7.1.1, the latest bugfix revision of CircuitPython, and is a new stable release. It has fixes for RGBMatrix on RP2040 and PDMIn (microphone input) on SAMx boards, such as Circuit Playground Express. There are no other changes; unless you are affected by these problems, you do not need to upgrade from 7.1.0.

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 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).

Documentation

Documentation is available in readthedocs.io.

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, atmel-samd, cxd56 (Spresense), espressif for ESP32-S2, nrf,raspberrypi, stm for the F4 family are stable. stm for other STM chip families is being actively improved but may be missing functionality and have bugs. broadcom (Raspberry Pi), espressif for ESP32-S3 and ESP32-C3, litex and mimxrt10xx are in an alpha state and will have bugs and missing functionality.

Changes since 7.1.0
