The UART to USB cable didn’t work out. It’s not possible for humans to connect those wires to the Molex header, and the only option to make it work is to buy a Molex 5268 connector from somewhere (nowhere in the UK sells them, so I guess abroad for lots of money).
Repeated note to all potential sellers of ARM “development” boards: Put a fscking serial port on it.
