IO Breakout board


Good day John,

Some time ago i ordered the breakout shield for an uno.

After some troubleshooting I found out that the ground pins are not working. (the are connected to each other but not to the pins connected to the Arduino)
So I checked the design files to see if its my fault. But the design files are missing.

Can you please check the design and if they are correct tell me which of the ground pins is used?

Also It would be better to have 2 connectors instead of 3.

Ping 10 and above are useless when using ethernet. But can be used with your relay shield.
Pin 0 and 1 are not that easy to use.
Connector 1: D2-D9
Connector 2: A0-A5 (optional with D0/D1)
