PCI-E to 4-channel SATA 3.0 Adapter for CM4 IO Board

The Compute Module 4 IO board includes a 1x PCIe Gen 2.0 slot allowing you to add additional hardware to your CM4 projects.

This PCI-E to 4-channel SATA 3.0 adapter board adds a low latency, low-power AHCI controller to your CM4 IO board, allowing you to build up various high-speed IO systems, including servers, high-capacity system storage or surveillance platforms.

In addition to the power supply from the PCI-E interface, there's also a power header for an external 5v/12v input. LED indicators are onboard for each SATA channel, flashing whenever data is read/written.

Note

• The module is PCIe Gen 3 interface but the Raspberry Pi CM4 is PCIe Gen 2 interface, therefore the max speed is 5Gbps
