Hello,

just a quick question about the Viola carrier board: What is the system for the pin numbering? Is it as written in my screenshot, so starting with 1 in the lower left corner? I just want to use the serial uart output as mentioned in the screenshot, it would be nice if you could tell me if I´m correct, because I couldn´t find the numbers in the datasheet.

Yes it’s a standard 2 rows header numbering. Square marked pin has number 1 and it starts odd numbers row. You can see pin numbering at Altium Designer Viewer (Viola Carrier Board | Toradex Developer Center). Click on “PCB” then zoom on connector.
