Raspberry Pi M.2 HAT+ 擴充板 | PCIe to M.2

描述

Raspberry Pi M.2 HAT+ 擴充板 | PCIe to M.2  

現貨供應。

 

Raspberry Pi M.2 HAT+ 讓您能夠將 NVMe 設備和 AI 加速器等 M.2 週邊設備連接到 Raspberry Pi 5 的 PCIe 2.0 介面，支援 NVMe 設備和 PCIe 週邊高達 500 MB/s 的資料傳輸。

《M.2 鍵位和介面對應》

不同的鍵位（Key）有常用的週邊設備對應和防呆鍵位，如下圖。

舉例來說，如果是支援 M Key，通常會是使用 PCIe×4 或是 SATA 和 SMBus 等裝置。而也可能同時支援兩種不同的鍵位，如下圖。

舉例來說，如果同時支援 B Key 和 M Key，就可以做成 B+M Key；如果同時支援 A Key 和 E Key，就可以做成 A+E Key。

 

《Overview》

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.
