Is there a Scematic for T4.1? Missing SMD Part

[sennert]

Hello,

I just wanted to try out the Ethernet on the new Teensy 4.1.
Unfortunately I desoldered one of the SMD components and lost it. Is there a scematic available? Or can somebody tell me what I need to replace the missing part?
It's probably a cap...




Also is there a backside available from the Pinout card?


Thanks alot, cheers

Hi sennert.
You can find the schematic in post #7 here.
For the backside pinout you could check post #658 from here.

Amazing, Thank you very much!

That part is a 2.2uF capacitor, specifically this one on the schematic.

[sennert]

super! thank you very much, Paul.

Connected the 6 Pins directly to a Magjack without any of the recommended/optional parts from your breakout and it's working
(also without the 2.2uF Cap that I accidentally removed)

To which Pin does the Cap on the Ethernet Breakout connect to (I mean the one that is not optional: Capacitor, 0.1uF, 805) ?

[PaulStoffregen]

That 0.1uF capacitor connects between the transformer center taps and GND.

thank you!
