I’ve installed a 4G Mars in a uctronics rack mount series U6246.
Powers up fine via POE and am trying to get the status OLED working but it’s failing to find the i2c device that would be connected to pins 3,5 (i2c1).
Is there a full GPIO chart?

Looks like I was being an idiot and didn’t realize I didn’t have root privileges.
The solution is to edit the device from /dev/i2c-1 to /dev/i2c-0 in U6143_ssd1306.c and rerun make.
