ADM_52840 Breakout board for Holyiot_18010 by Atelier du Maker
The ADM_52840 is a Breakout board to test an NRF52840 module from HolyIOT. Nothing very difficult, apart from the soldering part which requires a stencil in order to solder all the pads of the module. However, since internal pads are routed using vias, it’s possible to solder them all with a good soldering iron. It requires a J-link type programmer. An ST-Link V2 should be suitable or the J-Link of Nordic DK boards.

CircuitPython 9.2.6
This is the latest stable release of CircuitPython that will work with the ADM_52840 Breakout board for Holyiot_18010. Use this release if you are new to CircuitPython.
On nRF boards, CircuitPython 8.2.0 and later require UF2 bootloader version 0.6.1 or later. Older bootloaders cannot load the firmware. See Update UF2 Bootloader below.

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.
