Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage:
1. To avoid electrical shock, always disconnect the power from your PC chassis before you work on
it. Don't touch any components on the CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The sudden rush of power as you
connect a jumper or install a card may damage sensitive electronic components.

◼Audio Port
Green connector means LINE OUT, and pink connector means MIC IN.
◼Digital I/O Port (Optional)
Guide:
1. DI ports have default high (3.3V) voltage. Users have to input a low (GND) voltage to give a
trigger signal.
2. Users can define high (3.3V) or low (GND) voltage by themselves for the output DO ports.
3. VCC port always provides DC high (5V) voltage.
4. GND port always provides DC low (GND) voltage.
◼ANT
These are reserved holes for SMA connectors of antennas. When a customer selects a 4G or a
Wi-Fi module, they will need the ANT hole for plugging in a SMA connector.
