MT7688K

1T1R 802.11n Wi-Fi platform for repeater, storage, IPC, audio and IoT gateway applications

MediaTek MT7688K integrates a 1T1R 802.11n Wi-Fi radio, a 580MHz MIPS® 24KEc™ CPU, 5p FE switch or 1p fast Ethernet PHY, USB 2.0 host, PCIe, I2S/PCM and multiple GPIOs. It includes 8MB memory and is provided with eCos for compact router, repeater, IoT bridge, storage and audio applications. An additional 802.11ac chipset can be added to build a 802.11ac dual-band concurrent IoT gateway.
