Hi - NEWB here !
So I want to stack a Pi 4 B, 2xIOPlus HATs and a GPIO connector HAT. There's not a lot of clearance for putting connectors on the bus 1 & 2 connectors. For my successful experiments I've soldered a 2x10 pin header, and used breadboard jumper cables.
For the finished project I am thinking of cutting down a 2x20 right angled female socket and using those, but I'm then reduced to breadboard style jumpers to connect to the devices - anyone got any better ideas (other than the obvious of soldering wires direct to the IO Plus board) ?
