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.

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.

Seeed PCIe 3.0 Dual M.2 HAT for Raspberry Pi 5
The pictures on the wiki are not the clearest (every fixing appears to be white in the pictures, but helpfully, the ones in the packaging were different materials/colours. Nice there is also spares of everything.

Seeed PCIe 3.0 Dual M.2 HAT for Raspberry Pi 5
Does work but awkward to install and high power consumption. Instructions on Seeed wiki don't match the contents delivered. The wiki shows some short nylon spacers which you thread screws through to secure to the base standoffs. Actual pack was missing nylon spacers but instead had metal spacers with a stud and tapped hole, did still have the long screws but they don't seem to have any use. End result is OK, but fiddly to install. Especially since there are some tiny spring loaded studs which have to exactly match up to the base of the Pi GPIO power pins. Main issue though is power consumption. Pi-5 with Pimoroni base and one NVMe drive draws around 0.5A when fully booted and quiet with no GUI. Same NVMe drive using this base draws over 0.9A under the same conditions, nearly doubling the power consumption! Since this was meant for a battery-powered application that's disappointing. To be fair if you are then going to install a Hailo-8L as well, a prime use for this base, then maybe you aren't so power conscious and it does work at the speeds advertised. So maybe 3* is a little harsh but can't bring myself to give 4* for something so unexpectedly power hungry.
