MDBT50Q-DB demo board is designed for quick testing and debugging without building your own board. The board is only available with MDBT50Q-1MV2 (Chip Antenna) module.
Raytac nRF52840 module spectrum covers MDBT50Q-1MV2, MDBT50Q-P1MV2 and MDBT50Q-U1MV2 series with Chip Antenna, PCB Antenna and u.FL connector for External Antenna option for selection.

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.
