SDIO is an extension of the SD model interface, this interface besides can connect SD card, support the SDIO interface devices can be connected such as interface SDIO WiFi module, make the device extension of wireless local area network communication function,
SDIO interface is based on the SDIO Wifi module interface of wi-fi standard embedded module, built-in IEEE802.11 wireless network protocol stack and TCP/IP protocol stack, data can be achieved with householder platform through the conversion between SDIO mouth to the wireless network,
The working principle of SDIO wifi interface module
SDIO WiFi interface module
The WIFI module is single mode of wireless local area network (WLAN) and bluetooth solutions support 1 x 1, 802.11 a/b/g/n/ac WLAN standard, is designed to provide superior WLAN and low energy consumption technology integration,
The product is based on low cost, low power consumption, in line with the IEEE 802.11 a/b/g/n/ac module of international standard design, compatible with different vendors 802.11 a/b/g/n/ac wireless AP network access points, support 2.4 GHz/5 GHz dual mode of WLAN to choose, the module provides WiFi (SDIO V3.0 interface), the corresponding interface,
Users can use the WIFI module through the embedded hardware SDIO interface efficient and quick extension of wireless local area network communication function, effectively shorten the product development cycle, lower development costs,
