DFRobot M.2 M Key to PCIe3.0x16 Graphics Card Extension Cable (Compatible w/ LattePanda Sigma)
Description
- DFRobot M.2 M Key to PCIe3.0x16 Graphics Card Extension Cable (Compatible w/ LattePanda Sigma)
- Enhances performance with external graphics card support
- Prevents signal loss with EMI-shielded conductors
- Offers plug-and-play setup without driver installation
- Supports independent power with included SATA power cord
- Flexible design allows bending and folding without damage
The DFRobot M.2 M Key to PCIe3.0x16 Graphics Card Extension Cable (Compatible w/ LattePanda Sigma) is designed to enhance the performance of LattePanda Sigma by facilitating the connection of an external graphics card or PCIe device. This extension cable features a PCIex16 card slot and employs a differential signal hole-free design, ensuring no signal attenuation or interference due to parasitic capacitance and inductance. It offers a plug-and-play experience without the need for driver installation.

The cable utilizes metal-shielded wires and advanced EMI-shielding conductive polymers to maintain stable signal transmission. The use of new materials for EMI shielding allows the wire to be flatter, bendable, and foldable without compromising functionality. Additionally, the adapter card supports an independent power supply and includes a 15-pin SATA power cord, simplifying the setup process by eliminating the need for extra wiring.
Note: Ensure correct orientation when connecting the wire to avoid damaging the device. Handle the socket carefully to prevent disconnection of socket pins, and avoid bending or pulling within 2cm of the welding points. Signal attenuation may occur depending on the signal drive capabilities of various motherboards and devices.
