LattePanda M.2 M Key to PCIe4.0x16 Extension Module

This is an M.2 M Key to PCIe4.0x16 graphics card extension cable for LattePanda Sigma. It has a PCIex16 slot, hole-free differential signal design (no signal attenuation/interference from parasitic capacitance/inductance), is plug-and-play (no drivers needed), and pairs easily with external GPUs/PCIe devices to maximize Sigma's performance. We use metal-shielded wires and advanced EMI-shielding polymers for stable signals, with a flat, bendable design. It also supports independent power via a 15-pin SATA cord—no extra wiring hassle.
