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 Overview Raspberry Pi 5’s single-lane PCI Express 2.0 interface is exposed on a 16-pin, 0.5 mmpitch FPC connector; the M.2 HAT M Key, in both its standard and compact variants, 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 (standard and compact variants) and 2242 (standard variant only) 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. The standard Raspberry Pi M.2 HAT 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. The Raspberry Pi M.2 HAT Compact is designed for use with the Raspberry Pi Case for Raspberry Pi 5. The Compact form factor enables you to connect M.2 M key peripherals with the 2230 form factor to Raspberry Pi 5, while allowing space for the case’s integrated cooling fan.
