Raspberry Pi launches the M.2 HAT+ for Raspberry Pi 5, enabling high-speed NVMe and AI accelerator connectivity via PCIe 2.0 interface. Its release not only enhances the capabilities of the Raspberry Pi 5 but also fosters a broader ecosystem of high-quality PCIe accessories.
The Raspberry Pi Foundation has announced the launch of the M.2 HAT+, an innovative accessory designed to expand the functionality of the Raspberry Pi 5. This new add-on enables users to connect M.2 peripherals, such as NVMe drives and AI accelerators, to the Raspberry Pi 5’s PCIe 2.0 interface, facilitating data transfer speeds of up to 500 MB/s.
Raspberry Pi M.2 HAT+
Key Features and Design
The M.2 HAT+ serves as a mechanical adapter, converting the Raspberry Pi 5’s 16-pin, 0.5mm-pitch FPC connector to an M.2 M key edge connector. It supports devices in the 2230 and 2242 form factors and can supply up to 3 A of power to connected peripherals. This ensures compatibility with a wide range of high-performance components, making it an essential tool for both hobbyists and professionals.
Enhanced Connectivity
Conforming to the Raspberry Pi HAT+ specification, the M.2 HAT+ is designed for seamless integration with the Raspberry Pi 5. The device is autodetected by the latest Raspberry Pi software and firmware, simplifying the setup process. It also features power and activity LEDs, providing clear status indicators during operation.
Development and Compatibility
The launch of the M.2 HAT+ is the result of extensive testing and refinement and has been whispered about at exhibitions and events since at least mid-2023. The Raspberry Pi engineering team worked diligently to ensure compatibility with a variety of NVMe drives and other peripherals. During the development process, the team addressed numerous issues, such as startup timing problems in drive firmware, to ensure reliable performance with the BCM2712 PCIe controller on the Raspberry Pi 5.

Supporting Accessories
The M.2 HAT+ is supplied with a comprehensive set of accessories, including a ribbon cable, 16 mm stacking header, threaded spacers, screws, and a knurled, double-flanged screw. These components facilitate easy installation and ensure that the M.2 HAT+ can be securely attached to the Raspberry Pi 5, even with the Raspberry Pi Active Cooler in place.
