      Hello all! I received a lot of support from this forum trying to get this project off the ground, so I figured I should share some of the results as well. Warning: this project is stupid. Maybe the dumbest thing I've ever spent my time on. But...

      Well, bad news. Back to 9 blinks and the capacitor is still definitely installed. Seems like I may have torched some other traces with my bull-in-a-china-shop mentality. Definitely connect Pin 5's trace, but per the schematic I don't think that...

      Upon further inspection after removing the teensy from the protoboard, it seems like I've blown up C28. Not certain what that would have to do with my problem but I'll try dropping another 2.2uF cap in its place:

      Hi, my Teensy 4.1 is doing the 9 red LED blinks on the bootloader LED (I think?) when powered up. It will not enumerate as a USB device when plugged into the computer. Per this thread...
