Papyr is a connected e-paper display powered by Nordic Semiconductor’s nRF52840 chip. You can read more details on the hardware, and installation instructions for Circuitpython on the docs site for Electronut Labs.

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.
Latest version: 0.3.2
The bootloader allows you to load CircuitPython, Makecode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
Updating the bootloader on nRF52840 boards is an involved process right now. Follow the instructions in this README. It is not necessary to update on each release if your bootloader is working fine. Read the release notes on GitHub to see what has been changed.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
