Product Overview


This is a WLAN 802.11ax (WiFi 6) SDIO M.2 2230 (KEY E) Module, 802.11ax WiFi 6 allow Increased capacity, faster speed, better coverage connections, improve the battery life of IoT sensors, and extend the range of Wi-Fi signals. By implementing the new 802.11ax standard with its unique features such as OFDMA, 1024QAM, Target Wake Time (TWT), and spatial reuse, the WNFB-266AXI(BT) module enables smooth streaming of high-resolution videos, fewer dropped connections and faster connections farther away from the router and in dense environments..



The Wi-Fi and BT 5.0 functionalities module with seamless roaming capabilities and advance security. The 802.11ax M.2 2230(KEY E) module can support Multi-User MIMO (MU-MIMO) technology to increase channel capacity. Furthermore the included SDIO interface for Wi- Fi, UART/ PCM interface for BT.



WNFB-266AXI(BT) module can support the Soft AP mode and Station (Client) mode. The product can be connected to a wireless network as a Client, while also creating a separate network as an AP for other devices to connect to it.

Suitable Application


Applications include medical devices, security

systems, industrial PC, Remote control, digital signs, STB, embedded / tablet PC’s, smart devices, Smart manufacturing, shop, Home, TV, etc.
