-
This 4 legged chip blew after i was messing with my z end stop as it stoped working now when i connect my paneldue 5 it wont turn on or when i connect to my pc it will connect with difficulty and will say one command waiting if try to do something like a homing move if it helps i was also trying to connect my paneldue sd with an old cable from my printer
My guess is i bridged 3.3v and ground would i just need to replace this chip if so where can i get it thanks in advance ***- bolded text***

which revision of the duet board is it? from the orientation it is not one of the current ones so the part may differ.
edit: any supplier like digikey mouser farnell rs arrow and so on, ref for schematics and part numbers https://github.com/T3P3/Duet/tree/master/Duet2/Old versions

@bearer oh sorry forgot to put it in there its a duet 2 maestro v1.0

maestro v1.0
ehm, it kinda shows on the picture when one opens ones eyes...
schematics are mostly in the same place though. https://github.com/T3P3/Duet/blob/master/Duet2/Duet2Maestro_v1.0/Duet2Maestro_Schematic_v1.0.pdf
and the part is a AP7361C-33E-13
edit: you can desolder the part and inject 3.3v (current limited to 200mA) to any 3.3v pin to test the board before ordering the part, cpu and ethernet run off 3.3v. most likely of you just shorted 3.3v and ground the damage should be limited to that regulator.

@bearer thank you I'm going to order this part and hope it fixes it
