Is it possible/practical to add a trace from PB22 to pin 3 connector J2 which is apparently unused? Making PB22 accessible would allow a high precision oscillator to be fed to XOSC1, assuming I’m reading the datasheet correctly. There appears to be a possible path with minimal effort.

Thx,

bob

Hi bob.

You could add a jumper wire that runs from the SAMD51 over to that unused pad but we don’t have room to run a trace and that could potentially cause issues with shields made for the Feather layout since that pin is designated as analog reference.
