This is an M.2 M Key to 4-way PCIe expansion board specially prepared for LattePanda Sigma users. It effectively solves the problem of insufficient PCIe interfaces. It is driver-free and plug-and-play. It can be used with the Sigma motherboard to expand 4 channels of PCIe interfaces to connect external multi-channel graphics cards or other PCIe devices.

The expansion card uses a 4-layer circuit board, which has strong anti-interference ability and effectively ensures the stability of PCIe high-speed signal transmission, data integrity, and impedance matching. In order to enhance operational stability, the chip is also equipped with an aluminum alloy heat sink to provide better heat dissipation.

Note: All 4 ports are PCIex1, transmitting PCIe signals, not USB data! It must be used with a PCIex1 to PCIex16 adapter card to connect an external PCIe device.
