I could find the schematics in PDF. And I assume they are made with Altium. But I can’t find the Altium files?
Are those not public available?
Yes they are made in Altium but they are not publically available unfortunately.
Strange, it thought it was Open Source hardware.
We have only open schematics. We do not comply with Open Source Hardware requirements for multiple reasons. It is unfortunatelly not viable for us to release full hardware documentation at the moment.
So, do I understand correct that if we pay, we can have them?
That is rather question on our sales department. Feel free to contact them on firstname.lastname@example.org.
In general it is because we do not want clones not because we expect anyone to pay.
