WizFi630S is a gateway module that integrates 1T1R 802.11 Wi-Fi, a 580MHz CPU, Ethernet PHY, USB2.0 host, SD-XC, I2S, I2C and more GPIOs.

WizFi630S enables a device with serial interface to connect to LAN or WLAN for remote control, measuring, and administration. WizFi630S can also work as an IP router because of its internal embedded switch.

WizFi630S supports interfaces like Serial (UART), LAN, and Wi-Fi(WLAN). Functions such as Serial(UART)-To-Wi-Fi, Serial-To-Ethernet and Ethernet-To-Wi-Fi are supported by scripts and/or commands in OpenWRT. Users can connect to WizFi630S’s internal web server or use the serial commands for simple Wi-Fi settings - not only for serial devices but also 8/16/32 bit micro controllers can use UART for simple Wi-Fi settings.

WizFi630S can significantly reduce the procedures for wireless module design, testing, and certification; WizFi630S can be an ideal solution for users who lack wireless network experience. WizFi630S follows the 802.11b/g/n standard and supports up to 150Mbps speed in wireless interface. WizFi630S can be tested with an evaluation board and all documents are available online.
