GPIO Header
The conga-SMC1 provides up to eight GPIOs on connector X37. All I/O signals have 1.8 V level. The 3.3 V is provided through a 500 mA
resetable fuse.

+ 3.3 V
3.3 V supply (runtime)
Note
1. On x86 variant, pin 1 is not connected because GPIO4 is used for HD audio reset.
2. Pins 2 and 3 are for GPIO12 and GPIO13 respectively because we used GPIO5 and GPIO6 for fan control by default.
