Linklt Smart 7688 Duo is an open IoT dev board that runs OpenWrt


The LinkIt Smart 7688 Duo is an Arduino Yún-friendly board powered by an ATmega32U4 and MediaTek MT7688.


The collaboration of MediaTek Labs and Seeed Studio recently unveiled the LinkIt Smart 7688 dev board targeted at IoT applications. The platform gives users a choice between the new LinkIt Smart 7688 or Smart 7688 Duo, both of which run OpenWrt Linux on the 580MHz MediaTek MT7688AN CPU, with the latter equipped with an ATmega32u4 for Arduino compatibility.

The LinkIt Smart 7688 is designed to enable the prototyping of feature-rich applications for the connected home or office, such as Wi-Fi IP cameras, surveillance devices, smart appliances and wireless gateways. Not only does the platform boast 128MB RAM and 32MB Flash, it allows developers to create apps using Python, Node.js and C languages. As noted, the Duo can even be programmed with the Arduino IDE for real-time control of peripherals and users can take advantage of the MediaTek Cloud Sandbox for IoT data collection, visualization and analytics.

The boards each include with a microSD slot, a microUSB host and a microUSB port for 5V power input. On the Duo, the second microUSB socket can also handle data signals. Measuring only 61mm x 26mm in size, the Linkit Smart 7688 Duo offers pin-outs for GPIO, I2C, SPI, UART, PWM and fast Ethernet, as well as ADC and SPIS.

There are three breakout boards available for the standard LinkIt Smart 7688, and Seeed provides another three options for the Duo: an Arduino breakout, a Grove accessory breakout and a Grove Starter Kit with a variety of sensors and I/O modules.

The platform ships with open specs and can be found on Seeed Studio’s page here.
