Overview

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 converts between 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 autodetected 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.
