I am working on a project with Teensy 4.1 that requires 53 I/O pins. After working on the project, I have come to realize that the SD and QSPI pins are not easily accessible in a PCB. Has anyone connected these pins to PCB?
I don't think I will need the extra memory or an SD card, so their primary uses are not important to me. I just want to use them for digital I/O. Thanks.
