The M.2 (NGFF): a Further Examination
M.2 is the modern standard, offering higher speeds and more features than its predecessors. The pinout varies based on the "key" of the M.2 card. The keys dictate what functions the card performs.
- Key A: Typically supports Wi-Fi and Bluetooth.
- Key B: Supports SATA or PCIe.
- Key E: Supports Wi-Fi, Bluetooth, and WiGig.
- Key M: Primarily used for SSD storage, but also for high-speed PCIe devices.
- Key B+M: Supports both B and M keys.
The number of pins varies depending on the key. Some M.2 cards have 75 pins or more. Since the exact pinout depends on the key, one must refer to the specific datasheet for the Wi-Fi card to get accurate information. M.2 cards use significantly fewer pins than Mini PCI-e cards.
**(Note: Accurate pinout diagrams for specific M.2 cards are often found in the card's datasheet or technical documentation. Due to the wide variety of M.2 key configurations and card manufacturers, providing a generic pinout is not practical. Therefore, the specific pinout data for M.
