Hi,
does anyone know the pinout of the 11+2 test pads on the bottom side of the Teensy 4.1? Two of them connect to the USB device port (D+, D-), but I was not able to find anything on the other 11. I would need a few more I/Os, and maybe I could use some of these pads?

See you

On the Teensy 4.1 page, scroll down to "Test Points" near the very end of the page. You'll find this image. Look for the test points on the schematic for details of how they're connected. These names should match up with names you'll see on the schematic.

For more I/O, only the AD_B0_00 signal could be used. One more pin is more than none, but all the others are power supplies or special signals you can't use to get more I/O.
 
Hi Paul,
oh, what kind of sorcery is this? Scrolling to the end of the page must be one of the secret tricks, like looking at the second page of Google search results.

Thank you very much for pointing out what should have been obvious.

I'll contact AD_B0_00 and see if I can use it.

See you
Flo
