PCI-E 1X 1 TO 3: If you need more than one PCI-E x1 slot on the motherboard was not so much, it contacts you you can think about it. It consists of two parts, a main board, an interface installed via PCI-E X1 on the motherboard, two equipment boards, both connected together via a USB 3.0 cable. The peripheral card also uses the United States Pericom Pericom PI7C9X bridge chip, to switch between PCI-E and PCI-E. But even USB 3.0, but also the theoretical bandwidth 5Gbps (625MB/s), one in four Then remove the loss would only be 150MB/s, and even PCI-E 1.xa single-channel bandwidth also 250 MB/s, so that stuff is more than enough to give you the best locations, there won't be enough bandwidth, not just for the performance requirements of the location. Therefore, the transferred PCI-E slot is the best version above 2.0, version 3.0 is better. Multiple divided PCI-E 1X slots are all in gen2 mode, even if gen1 previously, it may be ok! Special APP function; Route planning: Draw a flight path on the screen, and the drone will fly autonomously along the specified path; Motherboard size: (LXWXH) 9.60 x 6.40 x 1.30 cm / 3.78 x 2.52 x 0.51 inch; PCI-E card size: (LXWXH) 11.80 x 6.50 x 1.90 cm / 4.65 x 2.56 x 0.75 inch;USB cable length 60cm / 1.97ft;color: Blue;Material: PCB installation: 1. The first step, the first of the USB PCIe card plugged into the PCIe slot of the motherboard. 2. Use a USB3.0 data cable adapter to connect the ends of the two USB ports. Plug in the power supply. 3.The third step: After the above two steps are completed, first insert your PCI-E card without hurrying, start the computer to see if your computer has been identified on the card riser card, if you can't find the card, repeat the above operation (Note: The first time you insert the card to start the computer, in the general system, you will be prompted to install new hardware, such as "PCI standard PCI-to-PCI Bridge", you must wait for it to automatically install the complete and individual antivirus software will prevent the installation of these files, note ignored), when your computer has been recognized the card, PCI slot blue LED on light normal, computer equipment The manager in the system device will show an increase of several PCI-to-PCI bridge standard PCI 4. After completing the above three steps, turn off the computer, plug in your PCI-E card, to pay attention not to insert the opposite, then boot into the system, install the driver Package Contents: 1 x motherboard 1 x PCIe card 1 x USB white cable 1 set x screws Only the above package, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The allowable measurement error is +/- 1-3 cm.
