Nordic nRF54LM20 Development Kit (Zephyr) by Nordic Semiconductor
The nRF54LM20 DK is Nordic’s development kit for the nRF54LM20A and nRF54LM20B wireless SoCs. It exposes the SoC’s interfaces on headers and includes a built-in SEGGER J-Link programmer/debugger, four user buttons and LEDs, power-measurement points, and 8 MB of external flash.
This CircuitPython download uses the experimental Zephyr port. See Nordic’s development-kit page and getting-started instructions for the board’s connectors and programming setup.

CircuitPython 10.4.0-alpha.2
This is the latest development release of CircuitPython that will work with the Nordic nRF54LM20 Development Kit (Zephyr).
Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.
Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
