The new Raspberry 5 has a new UART port, which is great because the first 4 Pi's used the hardware serial as a UART - which made debugging hard when using something like a GPS.

However, unlike the GPIO header UART, this connector is SMT, and much smaller than 0.1" pitch. While we can always contact the Pi folks for a part number, let's figure out what connector it is just using a pair of calipers - then find a cable that will plug in that we can use to get that tasty RX/TX data out!
