Wallys developed and designed the wifi7 M.2 moudle, using Qualcomm QCN9274 chip, currently there are two versions
1. DBDC: supports both 2.4G and 5G frequency bands.
2. DB: Support 5G or 6E frequency band.
Let's take a look at the introduction of the M.2 moudle and the use of the QCN9274 chip:
On the Wi-Fi motherboard, the M.2 card is used to install the wireless network card (Wi-Fi module). The M.2 interface provides a high-speed connection channel, enabling the wireless network card to perform data transmission and communication with the motherboard.

By installing an M.2 wireless network card, users can add wireless network connection capabilities to motherboards that do not have integrated Wi-Fi functions. In this way, the user can connect to the Internet through the wireless network and enjoy the convenience of wireless Internet access.
M.2 wireless network cards usually support multiple Wi-Fi standards and frequency bands, such as 802.11ac, 802.11ax (also known as Wi-Fi 6), etc. They provide faster wireless transmission speed and more reliable connection quality, which can meet the needs of high-speed data transmission and smooth network experience.
M.2 card (also known as Next Generation Form Factor, NGFF) is a standard interface for connecting internal storage devices. It is widely used in laptops, desktops, and other computing devices to connect devices such as solid-state drives (SSDs) and wireless network cards.
The M.2 card adopts the PCI Express (PCIe) bus and SATA (Serial ATA) interface standard, which has higher transmission speed and smaller physical size. Compared with the traditional connection method (such as SATA cable), the M.2 card More compact and flexible.
The size and key position (Key) of the M.2 card can be changed according to different specifications and functions. Common M.2 sizes are 2230, 2242, 2260, and 2280, which represent the length and width of the card in millimeters, respectively. The keys indicate the connection type and supported functions of the card, including PCIe x4, PCIe x2, SATA and other interfaces.
The main application of the M.2 card is as a system storage device for installing the operating system and storing user data. It is more popular than traditional 2.5-inch SSDs due to its higher transfer speed and smaller size. In addition, M.2 cards can also be used to expand device functions, such as installing wireless network cards, Bluetooth modules and dedicated accelerators, etc.
Qualcomm chip QCN9274 is a Wi-Fi and Bluetooth combination chip developed and produced by Qualcomm (Qualcomm). It is a member of Qualcomm's Snapdragon family of chips designed to provide wireless communication capabilities for connected devices.
