Hi! This is a really cool project. I was wondering how much the whole unit costs?

Also you mentioned 17 channels, but the PCB only has 10 clamp inputs. Where would I connect the other 7?

(Sorry for opening a issue, but I can't see the discussions tab)

Hi!

The unit cost (without the clamps) is around € 30, depending on where you source your PCB or components. The clamps then are about € 3 each.

You are right: I did not explain correctly how to reach 17 channels but I published everything in a rush. It has two expansion boards that can be placed on top of the main PCB. They are connected through standard header pins at the bottom and top of the PCB. In the documentation folder you will find all the schematics!
