Busy days at the moment, but I just wanted to document something that has annoyed me for some time. On several projects where custom hardware is too much of a job, I’ll use the Velleman KA05 shield.

It provides 6 relay outputs, 6 general input/outputs and 6 analog inputs via tiny, but functional screw terminals. There’s just one thing - they didn’t document it. Here’s a Pinout for this shield that tells you what pins on the Arduino UNO it’s connected to.

Velleman also sells this as the “VMA05: I/O SHIELD FOR ARDUINO” Module where you assemble it yourself. The pinout is the same for this one.
