With the v25.12 release of postmarketos, the Pinenote support is in a pretty good place. Although the device isn't in community yet, I backport fixes from edge so you don't have to. I've packaged hrdl's sway config under device-pine64-pinenote-sway-hrdl for those wanting an opinionated setup right away. I'll be working on optimising existing postmarketos UIs for eink displays in preparation for v26.06.
