The Raspberry Pi 5 is the first model in the Raspberry Pi series to support PCI Express (PCIe) .
In order for the Raspberry Pi 5 to recognize M.2-compatible devices, a PCIe to M.2 conversion board is required, but until now there has been no official Raspberry Pi conversion board.
The Raspberry Pi development team announced the development of an M.2 connection HAT from the beginning of the announcement of the Raspberry Pi 5. They then revealed that it was ready for production on May 14, 2024, and began selling the Raspberry Pi M.2 HAT+ for $12.
The Raspberry Pi 5's single-lane PCIe 2.0 interface is exposed on a 16-pin, 0.5mm pitch FPC connector. The Raspberry Pi M.2 HAT+ is a board that converts between this connector and a subset of the M.2 standard, supporting devices with Type 2230 and Type 2242 edge connectors.
The Raspberry Pi M.2 HAT+ can supply up to 3A to connected devices, with transfer speeds up to 500MB/s.
'Ideally, we would have launched the Raspberry Pi M.2 HAT+ at the same time as the Raspberry Pi 5, but we thought that rushing would waste money. In particular, we had unresolved questions about two spare pins on the 16-pin FFC connector. In early prototypes, these pins had I2C signals, but ultimately the Raspberry Pi PCIe connector specification assigned them to a fixed function, one as a power enable for powering downstream devices, and the other as a board detection and wake signal. While we were doing all this, we were testing various NVMe drives and other peripherals and investigating various issues. And of course, it takes time to write firmware and build the manufacturing processes, material pipelines and test systems required to produce tens of thousands of products per month. But all of this has been done. We are pleased that the product is now ready to be released,' he said.
Third-party M.2 connection HATs have existed for some time, making it possible to connect an M.2 SSD to the Raspberry Pi 5. In the following article, you can see the steps to attach a third-party M.2 connection HAT to the Raspberry Pi 5 and boot the OS from the M.2 SSD.
