One ROM 24 - Adding USB-C to a 0.75" x 1.25" PCB

I have previously said I didn’t think it was possible to add USB-C to the 24 pin version of One ROM - but in this video I prove myself wrong.

See why and how I go about adding USB-C to this tiny PCB, using the RP2354A with built-in flash and dropping down to 0201 passives.

As usual, everything is open source, and the design files are available on Github, so feel free to have a look and make your own. I have stock of these boards, so if you want one, check out the links below.
