Recently purchased an Explorer Hat Pro and am probably try to run before I walk but something I thought would work does not.
I have a USB to UART adapter and configure many of my SD cards this way. I naively thought that, using jumper leads, I could connect the RX and TX on the Explorer Hat Pro board to the corresponding connectors on the adapter cable would work - it doesn’t.
From an Ubuntu machine I used sudo screen /dev/ttyUSB0 115200 - all I get is unformatted screen output which doesn’t seem to make sense, I think it halts at a login section but keyboard entries are unreadable.
Obviously I am doing something wrong, haven’t tried a direct ssh as due to present location only one ethernet connection and Ubuntu’s Realtek WiFi on my machine is very unreliable.
