nRF52840 M.2 Developer Kit
nRF52840 M.2 Developer Kit is a versatile IoT prototyping platform, including the nRF52840 M.2 Module and M.2 Dock. You can use the developer kit to prototype your IoT products and then scale to production faster using the nRF52840 M.2 Module combined with your custom PCB hardware.
The nRF52840 M.2 Module is a removable M.2 E-Key form factor module based on the nRF52840 SoC, supporting Bluetooth 5, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary stacks.
The M.2 Dock extends the interfaces compared to the nRF52840 M.2 Module through an M.2 E-Key connector. This design also features a fully-integrated DAPLink debugger with Power Profiling, enabling you to program, debug and perform real-time current profiling of your applications without using external tools.

This is the latest unstable release of CircuitPython that will work with the nRF52840 M.2 Developer Kit.
Unstable builds have the latest features but are more likely to have critical bugs.

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. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
