Is there documentation on the unlabeled pads for the Teensy 4.1 board? Like the pads located in a row across the board between pins 27 and 38 for instance. I also couldn't find the pinout for the 5 pin USB connector header pads. I tried quite a bit of looking around, but I didn't have any luck.

Unlabeled pads ideal usage is shown here: pjrc.com/store/psram.html
For pin Numbers this by KurtE is the best way to ID them so far as a PDF or Excel sheet:: github.com/KurtE/TeensyDocuments

Yes - Wish there was a back page on the T4.1 card...
My quick print of my T4.1 extended card from the Excel document that @defragster mentioned,
I updated slightly, it may not show up overly well, but the pins between 27 and 38 match the end pins on T4
So From top(38) to bottom(27) Are: On/Off, Program, GND, 3.3V, VBat
My excel document image shows the the IO pins associated with the memory chip pads.
The 5 pin USB matches the pins for T3.6 So if you look at those pins from side closest to USB connector going toward the SDCard. Are (+5V, DM, DP, GND, GND)
