Yeah I discovered those a little while and got a ton of them on aliexpress, they are hard to get anywhere else. They sell ones with terminal connectors on both ends, like wire to wire not just wire to board, I use those all the time. I used to use candy block connectors but it’s hard to get good ones at a reasonable price. These pluggable connectors provide the same function plus you can disconnect stuff and swap things around.
The most common pitches are 5 mm and 3.81 mm
