Confused about what 40 Euros gets me?
I know it is all instructions and parts list. (been an engineer decades so can work out all sizes from your drawing dimension)
Electronics is my weak area, I read through this multiple times and it seems to suggest fully populated v2 PCB (ready to go when wires screwed in) and mentions touch screen (but that surely cannot be included in the price?).
would be good to see what physical parts come, and obviously the rest would be in the parts list to buy separately.
