5 GPIO3 6 GPIO7
7 GPIO4 8 GPIO8
9 GND 10 NC
Note: the pins for GPIO are bi­directional signals. To facilitate test and
application, the factory default value is that Pin1, 3, 5 and 7 are for TTL input
while Pin2, 4, 6 and 8 are for CMOS output. The factory default status is high
level while the voltage range for IO signals is 0­5V.
Fan Connector
The board provides one 1x4Pin CPU fan (CPUFAN1, Pitch: 2.54mm) and one 1x3Pin
system fan (SYSFAN1, Pitch: 2.54mm). Pay attention to the following three issues
when using the fan socket:
Ø
The current for fan shall not exceed 700mA (12V);
