@sycophantic Well, I might still need to ohm out the +Vbus, D+, D-, and Ground since they're not marked out on J6 which I'm guessing would be for a JST header for the USB cable, hopefully that's all she needs
@sycophantic hey what if I'm just misreading the labels and TR1 is for TRansistor, not TRansformer, and that's actually just kinda a ferrite bead on the USB lines? hmmmm. I mean, the two wires that have gotta be data lines stand out on the board, they go through that and then through R9 and R14 and cross under the STM32.
