Today I would like to introduce a wallys board: DR2G41

Linux,WiFi-modules,4-miniPCIE-slot

Adapter Card 4 x Mini PCIe Card 4 x M.2 Card

DR2G41 is an adapter card with four MiniPCIe and four M.2 slots. It can be used in a PC with a PCIe slot. Use this new  adapter to expand your connectivity and upgrade your device to use the latest miniPCIe and m.2 interface cards. Each  comes with both low and regular profile brackets.

Brackets include holes for mounting SMA connectors, or for using as cable exit holes.

Let's look at each moudle it can support.

AX200 NGW is a network adapter released by Intel in 2019 that supports wireless communication protocol 802.11ax (WiFi6), communication bandwidth 160MHz, MU-MIMO technology, OFDMA orthogonal frequency division multiple access (OFDMA).

DR600vx(Quaclomm qca9880/qca9882 chipset)

The difference between DR600vx and DR900vx is that DR600VX is 2x2 2.4G/5G, the chip can be QCA9880/QCA9882,DR900vx is 3x3 2.4G/5G, the chip can only be QCA9880.

Qualcomm QCA9880 is a highly integrated WLAN SoC that can be used in 5GHz 802.11ac or 2.4/5GHz 802.11n WLAN products. QCA9880 supports 3x3 MIMO and can be used for high-speed wireless data transfer applications. QCA9880 integrates a MAC, PHY, ADC, DAC, 3x3 MIMO wireless transceiver that supports multiple protocols. QCA9880 uses PCI-e interface to communicate with the outside world.

Qualcomm Atheros QCA9882 is a highly integrated wireless LAN (WLAN) system-on-chip (SoC) for 5GHz 802.11ac or 2.4/5GHz 802.11n WLAN applications. The QCA 9882 integrates an on-board cpu for the wireless LAN physical layer (Phy) and lower level Settings of the rf to offload the host processor to other tasks

The MT7915DAN is a highly integrated Wi-Fi A/D chip which supports 573+1201 Mbps PHY rate and Bluetooth combo. It fully complies with IEEE 802.11ax and backward compatible with IEEE 802.11 a/b/g/n/ac standards, offering feature-rich wireless connectivity at high standards, and delivering reliable, cost-effective throughput from an extended distance. Optimized RF architecture and baseband algorithms provide superb performance and low power consumption. Intelligent MAC design deploys a high efficient offload engine and hardware data processing accelerators which fully offloads WiFi task of the host processor. The MT7915DAN is designed to support standard based features in the areas of security, quality of service and international regulations, giving end users the greatest performance any time and in any circumstance.

Wallys has a history of 10 years, so it can be said that its hardware and software development design is very mature. It independently designs and develops software to support the current trend of wifi, including openwrt, MT and QSDK, which has been recognized and trusted by more customers.

There are many companies in the market that develop and design wireless motherboards (moudle, antenna), but for some reasons, the design and development is complicated and the cost is high, so more companies are not willing to take on such customers, and wallys can help you complete the project, which is also an advantage.

For example, if you buy a board from another company and you need wallys' moudle, but the board may not be compatible with moudle, this problem is troublesome, and wallys can help the customer solve the problem to some extent.

More customers can get technical support, so as to obtain more customer sources. This is not only for helping customers, but also for wallys' strong hardware and software development ability to gain customers' trust and support.

wallys also supports custom development if the client has a custom product project.
