This is a wifi module based on MTK (MediaTek) MT7688AN SOC chip solution. CPU frequency up to 580MHz, onboard 16MB Flash, 128MB DDR2 memory, 300M wifi speed, external USB 2.0 Host, GPIO, UART, I2S, I2C, sd card interface, SPI, PWM, Ethernet interface, wifi antenna interface.

The module is small in size, low in power consumption, low in heat generation, and stable in transmission performance of wifi and network ports. Run openwrt (linux) system, which can run stably for a long time. The peripheral circuit of the module is very simple. It only needs to add 3.3V DC power to start the system and can be controlled by WIFI. With a gold-plated pin header, it can be attached to the base plate very stably.

Can be used in smart home, IP camera, VOIP, remote control aircraft, remote video surveillance system, portable 4G router, audio intercom, simple WEB network server, simple FTP server, remote download, remote control visual car and many other applications.
