Overview RMS7688A IOT Rourer Module is based on MediaTek MT7688 chipset.the module requires only an external 3.3V power supply. MT7688 chipset integrates a 1T1R 802.11n Wi-Fi radio, a 580MHz MIPS® 24KEc™ CPU, 1-port fast Ethernet PHY, USB2.0 host, SD-XC, I2S/PCM and multiple low-speed IOs in a single SOC. The MT7688 supports two operation modes – IoT gateway and IoT device mode. The high-performance USB 2.0 allows MT7688 to add 3G/4GLTE modem support or a H.264 ISP for wireless IP camera. The IoT gateway mode also supports Zigbee/Z-Wave and Sub-1 GHz RF for smart home control. In IoT device mode, MT7688 supports eMMC, SD-XC and USB 2.0 in addition to Wi-Fi high quality audio via 192Kbps/24bits I2S interface and VoIP application through PCM, as well as peripheral interfaces including PWM, SPI host, 3rd UART and more GPIOs. Features ◆Embedded MIPS24KEc (575/580 MHz) with 64 KB I-Cache and 32 KB D-Cache ◆1T1R 2.4 GHz with 150 Mbps PHY data rate ◆Legacy 802.11b/g and HT 802.11n mode
