Connectors

The Pi 5 (and some Picos I think) have a UART connector. It seems to be a JST SH. The plug is, however, called JST SR. 1mm pitch.

Pi 5 UART max 921,600bps.

The same connector is use on some Picos and the Debug Probe for SWD.

Power

Does not do well on brownout. It didn't come back up when voltage dropped on high resistance cable. I found it with red LED on. Didn't power up properly until replugged, twice. There was also some data loss on the SD card.

According to a forum post, will not power on itself if powered on GPIO pins. It can run, but needs power button pressed.
