## Description

##Introduction This is an M.2 M Key to PCIe3.0x16 graphics card extension cable specially prepared for LattePanda Sigma users. It has a PCIex16 card slot, a differential signal hole-free design, and no signal attenuation and interference problems in parasitic capacitance and parasitic inductance. No driver installation is required, just plug and play. It can be easily paired with an external graphics card or PCIe device on the Sigma motherboard to maximize LattePanda Sigma's performance.We use metal-shielded wires and advanced EMI-shielding conductive polymers to ensure the stability of signal transmission. At the same time, we use new materials for EMI shielding to make the wire design flatter and can be bent and folded without affecting the use experience.In addition, the adapter card also supports independent power supply and is equipped with a 15-pin SATA power cord, which eliminates the trouble of additional wiring and is more convenient to use.Wiring Diagram of M.2 M Key to PCIe3.0x16 graphics card extension cable and LattePanda SigmaNote:1. Be sure to know the direction when plugging in the wire, and do not plug it in backwards or out of position to prevent burning the device. When plugging in, hold the socket of the device before plugging in the cord to avoid using too much force to disconnect the socket pins. Do not bend or pull within 2cm of the welding point between the two ends of the wire and the circuit board.2. Depending on the signal drive capabilities of various motherboards and devices, the signal may experience attenuation when an extension cable is connected. ##Features High-quality PCIex16 card slotPCIe3.0x4, bandwidth up to 32G/bpsUsing metal layer shielded wire, it can be bent and folded ##Specification Card slot: PCIex16Specifications: PCIe 3.0x4Transmission rate: 8GT/SBandwidth: 32G/bps(Max)Rated power: 75W (Max)Insulation resistance: 95MΩ-Km (Min)Differential impedance: 95ΩLine pair matching impedance: ±10ΩWorking temperature: -20°C ~80°CCord length: 20cm ##Documents Product wiki ##ShippingList M.2 M Key to PCIe3.0x16 Extension Cable x115-pin SATA power cable x1
