PCIEx1 to PCIEx16 Expansion Card - DFRobot

Introduction

This is a PCIex1 to PCIex16 adapter card specially prepared for LattePanda Sigma users. It has a PCIex16 card slot. No driver installation is required, just plug and play. It can be used with the M.2 M Key to PCIex4 expansion card (FIT0971) to add multiple external graphics cards to the Sigma motherboard to maximize Sigma performance!

The adapter card uses 3 power supply interfaces (6 PIN + 4 PIN + SATA 15 PIN) and a high-speed USB3.0 interface to realize PCIE high-speed data transmission, effectively ensuring the integrity of the data signal.

In addition, the adapter card is also equipped with a 15-pin SATA to 6-pin GPU power cable and USB3.0 data cable, which eliminates the trouble of additional wiring and is more convenient to use.

Note: The USB interface of the adapter card transmits PCIe signals, not an ordinary USB interface! It must be used with an M.2 M Key to PCIEx4 Expansion Board (FIT0971) to connect an external graphics card.

Connection Diagram

Note: When sigma needs to connect or unplug any powered equipment, sigma needs to be turned off and unplugged. It cannot be operated while it is powered on.

1. Install the M.2 M Key to PCIex4 expansion card on the M.2 port of the sigma motherboard. Both M.2 M Key interfaces of the sigma motherboard support this expansion card.

   

2. Install the graphics card on the PCIex1 to PCIex16 adapter card, and use the chassis power SATA-15Pin interface to power the adapter card.

   

3. Use a USB data cable to connect any interface of the M.2 M Key to PCIex4 expansion card to the PCIex1 to PCIex16 adapter card.

   

4. Connect the graphics card to the monitor through the VGA or HDMI interface, connect the sigma motherboard to the network cable, connect the sigma motherboard to the ATX to DC male power cord, and use the ATX-24Pin interface of the chassis power supply to power the sigma motherboard. (Since the system needs to install the graphics card driver, it must be connected to the Internet before booting. When sigma is booted, the system will automatically install the required driver)

   

5. After completing the connection of all devices, press the power button of the sigma motherboard. The system is installing the driver at this time, so the display will not light up immediately. Please wait patiently for a few minutes until the driver installation is completed and the display will light up normally and enter the system desktop. After booting, you can check the graphics card model through Display Adapter under Device Manager.

   

FAQ

After all devices are connected, the sigma startup display does not light up normally.

Reason 1: sigma is not connected to the network cable, and the system cannot install the driver for the graphics card.

Reason 2: The system is installing the corresponding graphics card driver, please wait patiently for a while.
