The Raspberry Pi M.2 HAT+ enables you to connect M.2 peripherals such as NVMe drives and AI accelerators to Raspberry Pi 5’s PCIe 2.0 interface, supporting fast (up to 500 MB/s) data transfer to and from NVMe drives and other PCIe accessories.

Raspberry Pi 5’s single-lane PCI Express 2.0 interface is exposed on a 16-pin, 0.5mm- pitch FPC connector; the M.2 HAT+ M Key is a mechanical adapter board that convert sbetween this connector and a subset of the M.2 standard. It supports devices that have the M.2 M key edge connector, in the 2230 and 2242 form factors. It is capable of supplying up to 3A to connected M.2 devices. The Raspberry Pi M.2 HAT+ conforms to the Raspberry Pi HAT+ specification and is auto-detected by the latest Raspberry Pi software/firmware. It is supplied with a 16mm stacking header and threaded spacers, so it can be fitted to a Raspberry Pi 5 with the Raspberry Pi Active Cooler in place.
