Common USB Interface WiFi Modules

New Year Gift for 2020, reply 【2】 in the background to receive the New Year gift

With the continuous rise and development of wireless networks, the application fields of WiFi modules are quite extensive, extending greatly from indoor to outdoor spaces. Currently, the WiFi modules developed and produced by SKYLAB can be roughly divided into three main series: USB WiFi modules, AP/Router WiFi modules, and UART WiFi modules. This article focuses on introducing several commonly used USB interface WiFi modules for novice engineers and designers who are new to WiFi modules.

The communication interfaces of WiFi modules include the following: USB, WAN/LAN, UART, I2S, I2C, SPI, SD, PWM; among them, the USB interface has a fast transmission rate, sufficient to meet the rate requirements of most peripherals, making it widely used in information communication products such as personal computers and mobile devices, and extending to other related fields such as photography equipment, digital TVs (set-top boxes), and game consoles. The USB interface in WiFi modules serves as a bridge for data communication between the firmware program inside the WiFi module chip and the operating system on the host.

USB 2.4GHz WiFi Module WG209

WG209 is a WiFi module that adheres to the wireless network standards of 802.11 n/b/g, designed with a USB interface to specifically enhance WiFi performance, widely applicable to various products such as gateways, set-top boxes, game consoles, printers, IP cameras, and more, which initially could not use WiFi functionality.

Dual-Band AC USB WiFi Module WG211

WG211 is a dual-band WiFi module with a physical transmission rate of up to 433Mbps, complying with IEEE 802.11a/b/g/n/ac wireless standards. It features 1×1 MIMO, with a transmission power of 18dBm in 11b mode; 15-16dBm in 11n mode; and 9-10dBm in 11ac mode, with a transmission distance of up to 150m. It can be applied to devices requiring high-speed WiFi transmission and featuring a USB interface.

Dual-Band AC USB Device WiFi Module WG217

WG217 is a highly integrated USB interface WiFi module that is compatible with IEEE 802.11ac 1×1 WLANs, with a data transmission rate of 433Mbps, providing excellent wireless connectivity even at longer distances! WG217 is designed based on safety, quality, service, and international regulations, aiming to provide the best performance for users under any circumstances, supporting AP/Ad-Hoc/Infrastructure modes.

Currently, both single-band and dual-band USB interface WiFi modules are in mass production to meet customer demand, with WG217 being favored by users in the video transmission field of smart home applications.
