R42SR M.2 Key-M PCI-E x4 Extension Cord for LattePanda Alpha & Delta & Sigma

This M.2 Key-M PCI-E x4 extension cable is crafted for LattePanda users who need PCIe3.0 full-speed signal transmission. It can achieve speeds up to 32G/bps, making it suitable for various applications such as high-speed network cards, capture cards, NVMe SSD hard disk cards, USB adapter cards, and PCI-E x4 interfaces.

Key to its performance is the differential signal without hole design, which eliminates issues like signal attenuation and interference in parasitic capacitance and inductance. This design element ensures a CAF micro short circuit-free operation and enhances the cable's durability. The use of high-quality materials and precision PCB craftsmanship is evident with the thickened copper at 1oz and gold fingers with sufficient gold content for excellent conductivity, reducing rust and minimizing blue screen issues.

Additional protection is provided by a PCB gasket with a 3mm thickness at metal welding points, secured by screws and hex nuts, making the cable robust, resistant to pulling, and interference-free. Its flexibility in bending and folding without hindrance to its function adds to its versatility.

The PCB design is intentionally dwarf and fat, ensuring it does not obstruct the graphics card, which simplifies installation and minimizes potential damage. Important to note is that the M.2 interface lacks inherent 12V power, thus requiring a connection to a 12V power PCIe card for optimal operation, while careful insertion is necessary to avoid damage or burning of the device.
