SABRE RevD J20 Gerber/board inconsistency

Hello!

 

I have downloaded the gerber files for the sabre board to determine the connector positions on the board.

There is a small inconsistency on J20.

 

when holding the board with the power-connector pointing north and ethernet connectors south:
Gerber Files: Pin 1 on J20 is top-right

Board: Pin 1 on J20 is bottom-right

 

Based on the schematic, Pin 2 of J20 is connected to GND. Resistive measurements show this is the top-right pin on the board and (just like the rest of the schematic for J20) is consistent with the board layout on the sabre hardware. Not with the gerber files.

 

Regards,
Lars
