GPIO Connector
The board provides one 2x5Pin GPIO connector, 4-channel input and 4-channel
output (Pitch: 2.54mm); the pin definitions are as follows:
Pin
Signal Name

Signal Name
1 GPIO1 2 GPIO5
3 GPIO2 4 GPIO6
5 GPIO3
6 GPIO7
7 GPIO4
8 GPIO8
GPIO1
9 GND
10 NC
Note: the pins of GPIO are bi-direction signals; to facilitate test and application, pin 1,
3, 5 and 7 are for input by default while pin 2, 4, 6 and 8 are for output.
LAN Port
The board provides two 2x7Pin 10/100/1000Mbps network pin headers (Pitch:
2.0mm); the pin definitions are as follows:
