Schematics

Changes from v1.2a

  • A bug was fixed, where connecting a VBUS powered device lowered the screen brightness (resistor R1318 changed to NC).

Changes with the Beta Edition

  • Due to the global pandemic early 2021 and the component shortage as a result, the magnetometer in the Beta Edition had to be replaced from an LIS3MDL to an AF8133L.

Known issues

  • It is not known if 3 issues of previous revisions are still present and if yes to which degree, or if they have been fixed by removing resistor R1318, see PinePhone v1.2#Backlight for some details. Please edit this page once this has been confirmed. Mind that there is currently a likely software-related bug present, which also causes the screen to flicker. The bug usually happens after abruptly shutting down the phone previously (for example by forcing it off), in contrast to powering it off.
