@dc42 said in 4.3 inch PanelDue v2.0:

@jakeblat yes that processor upgrade would work, however you would still be limited to running the version 2 firmware, which at some point we are likely to stop updating because the later version 3 has more RAM available.

You may wish to consider purchasing a new version 3 PanelDue Controller board to use with your existing display.

I was going by https://github.com/Duet3D/PanelDueFirmware/blob/master/whatsnew.md#limitations which suggested ATSAM3S4B could at least run v3.2.11 although not as fast as the ATSAM4S4B

I hadn't actually noticed the controller board was available on the shop standalone so I might just replace that with the latest version.
