Openwrt 300Mbps Wireless Module MT7628AN

Product Description

General Description

This Module use MT7628AN as Soc, has a IPX ANTA seat for alternative.What’s more,we lead out all function and I/O ports for expand.

The MT7628AN integrated a 2T2R 802.11n WiFi radio,a 580 MHZ MIPS 24KEc CPU,1port fast Ethernet PHY,USB2.0 host,PCIe,SD-XC,I2S/PCM and multi slow IOs.MT7628AN provide two operrtion modes-IoT gateway mode and IoT device mode.In IoT gateway mode,the PCI Express interface can connect to 802.11ac chipset for 11ac dule-band concurrent gateway.The high performance USB2.0 allows MT7628an to add 3G/LTE modem support or add a H.264 ISP for wireless IP camera.For the IoT device mode,MT7628AN supports eMMC,SD-XC and USB2.0. MT7628AN can support the WiFi high quality audio via 192Kbps/24bits I2S interface and

VoIP application through PCM. In IoT device mode,it further supports PWM,SPI slave,3^rd UART and more GPIOs.For IoT gateway,it can connect to touch panel and BLE,Zigbee/Z-Wave and sub-1G RF for smart home control.
