Velleman KA05 / VMA05 pinout

Velleman KA05 / VMA05 pinout

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.

Assembling the Prusa MK3

As a replacement for my DIY Reprap printer, I picked up a Prusa MK3. As I've done when assembling other printers, I did a timelapse video of the assembly.

I’m really happy with the purchase and the printer as done several long and complex prints with great quality already. A great workshorse for my workshop!
