PMW3389 Motion Sensor - Unavailable in Europe

[Pheggas]

Hello. I already wrote one discussion topic earlier regarding units. I came back as i printed the plastic parts and ordered some mechanical parts. However there is issue with the motion sensor part itself. It is made only by that one seller you are mentioning in the instructions PDF. I found the motion sensor itself on aliexpress but the board for it is custom made and i cannot find any "clone" or anything else regards it. I can order the sensor directly from the website but with the shipping, it is roughly 50$ which is a lot for that small sensor with even smaller board.
