So I mentioned in the UART Level Shifter post that a SPI Level shifter using the same ON Semi part would make a lot of sense. So I made one. It’s out for fabrication at OSH Park now, the third project in two days that I’ve sent to them. Hopefully they all make the cut for the panel that’s supposed to go out on the 19th. I’ll let you know how they go once I get them back! Check out the Github repo here.
