MT7688 core board PCB reference design MT7688 schematic data download
The MT7688AN system single chip can be applied to the bridging center of home automation. It integrates 1T1R 802.11n Wi-Fi radio, 580MHz MIPS® 24KEc™ CPU, 1-port fast Ethernet PHY, USB2.0 host, PCIe, SD-XC, I2S/PCM A single system-on-a-chip.
In IoT gateway mode, it can connect to an 802.11ac chipset via a PCIe interface and act as a dual-band 802.11ac synchronous gateway. The high-speed USB 2.0 interface allows the MT7688 to be connected to additional 3G/LTE modem hardware, or to an H.264 ISP as a wireless IP camera application. IoT gateway mode also supports hardware required for smart home applications such as touchpads, Bluetooth Low Energy, Zigbee/Z-Wave and Sub-1 GHz RF.
In IoT device mode, MT7688 supports eMMC, SD-XC and USB 2.0, and can play high-quality Wi-Fi audio through the 192Kbps/24bits I2S interface, or perform VoIP applications through PCM. At the same time, it also supports various peripheral interfaces, including PWM, SPI slave, three sets of UART and more GPIO interfaces.

mt7688晶片组整合了1t1r 802.11N Wi-Fi收音机，580mhzmips|24kec<UNK>cpu，1端口快速以太网phy，usb2.0主机，pcie，sd-xc，i2/pcm和多个低速iOS。The Mt7688 supports two modes of operation - multi-gateway and multi-device mode. In iot gateway mode, the pcie interface can be connected to an 802.11 AC chipset and used as a 11ac dual-band concurrent gateway. High-performance usb 2.0 allows mt 7688 to add support for 3g/lte modems or h.264 isp for wireless ip cameras. I have no idea. The iot gateway mode also supports touch panel and bluetooth low energy, zigbe/z wave and sub 1ghzrf smart home control. In iot device mode, mt 7688 supports emmc, sd-xc and usb 2.0 and wi-fi high, provides high-quality audio through 192kbps/24biti2s interface, provides voip applications through pcm, and peripheral interfaces including pwm, spi slave, 3 RD uart and more gpios.
