This PCIe 3.0 to dual M.2 HAT enables the Raspberry Pi 5 to access two NVMe SSDs, Hailo-8/8L (M.2 key B+M only), and Google Coral AI accelerators at PCIe 3.0 speeds. Features Dual M.2 Slots with PCIe 3.0 Speed: Utilizes the ASMedia ASM2806 PCIe 3.0 switch chip to ensure optimal performance, overcoming the limitations of PCIe 2.0. Stable Power Supply: Additional pogo pins provide extra power to ensure a stable high-speed connection. Multiple Size Support: Compatible with M.2 standard sizes 2230, 2242, 2260, and 2280. Back-mounted Design: Keeps the 40-pin GPIO free for use, allowing compatibility with other Raspberry Pi HATs. User-friendly Design: The S-shaped FPC cable does not obstruct the microSD card slot. Open Source Case: Seeed’s M.2 HATs are not compatible with the official Raspberry Pi case, but an adapted 3D-printable case (STP file) is provided. Applications Simultaneously supports AI acceleration and high-speed SSD storage Connects dual NVMe SSDs for large storage capacity Booting a Raspberry Pi from the SSD Specifications M.2 Slots 2 Max. PCIe Speed PCIe Gen3.0 PCIe Switch Chip ASM2806 M.2 Size Support 2280/2260/2242/2230 Max. Power Supply 5 V/3 A (max 3A: Pogo pin 2A + PCIe connector 1A) Cable FPC Assembly Method Back installation Dimensions 87 x 55 x 10 mm Included 1x Seeed Studio PCIe 3.0 to Dual M.2 HAT for Raspberry Pi 5 2x FPC cables (50 mm) 1x Screws & stud pack Downloads Wiki
