M5x pcb problem with thermofan setting
When turning on fan setting 1 ignition output Q14 ( ISL9V5036P3-F085 ) goes fully on and burns pcb traces.
LED7 stay lid, arduino output number 48 sends 5v even if its disconnected from pcb
Firmwares 202207 and 202305 have the same issue

Hmmnn, that doesn't make any sense. FAN output pin is supposed to be board default, and it's pin 47. Not pin 48.
