Water pump for mrfx1k80:
RD16 kit:
Optical encoder for wolf:
Had an issue with it. Seller mentions that it works with 5-24v input voltage. Wolf has 5v, and it didn’t worked. I’ve disasembled it and found out that there is 5v linear stabiliser, of course it’s unable to get 5v output from 5 volt input with linear stabiliser. Just removed it.
