Seeed PCIe 3.0 Dual M.2 HAT for Raspberry Pi 5

Featuring a PCIe 3.0 switch for faster read/write speeds, this bottom-mounted dual-NVMe add-on for Raspberry Pi 5 allows you to get the best performance out of NVMe drives and other M.2 modules thanks to the ASMedia ASM2806 PCIe 3.0 switch. Most M.2 HATs and add-ons for Raspberry Pi 5 typically use PCIe 2.0 packet switches. This add-on from Seeed uses the ASMedia ASM2806 PCIe 3.0 switch allowing greater read/write speeds, an example of which can be seen below. The add-on accommodates 2230/2242/2260/2280 M.2 standard-size modules. If booting from NVMe, we strongly recommend updating your firmware and bootloader first, using Raspberry Pi Imager. Note: SATA SSDs are not compatible - M.2 NVMe only. Raspberry Pi and SSD are not included. Performance Examples SD Boot + SSD Backup

Note: Hai08L only supports M.2 key B+M. NVMe SSD Compatibility There is still no definitive list of compatible NVMe SSDs for Raspberry Pi 5 via PCIe, however, the internet is full of discussions and examples highlighting which drives are likely to work. As a result, we always recommend the Raspberry Pi NVMe SSD. Features

* Dual M.2 Slot with PCIe 3.0 Speed: Uses the ASMedia ASM2806 PCIe 3.0 switch chip, overcoming PCIe 2.0 limitations

* Stable Power Supply: Additional Pogo Pins for extra power supply to ensure a stable high-speed connection

* Multiple Size Support: 2230/2242/2260/2280 M.2 standard size compatible

* Back-mounted Design: 40-pin GPIO free to use, compatible with other Pi HATs

* User-friendly Design: S-shaped FPC cable does not obstruct the micro SD card

* Open Source Case: Seeed M.2 hats aren't compatible with the Raspberry Pi official case, so they provide an adapted 3D printing case STEP file.
