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.
Table 26 X37 Pinout Description
Pin Signal
1 GPIO4/N.C
2 GPIO12
3 GPIO13
4 GPIO7
5 GND
6 GPIO8
7 GPIO9
8 GPIO10
9 GPIO11
10 + 3.3 V
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.
