New Open-source Wi-Fi Platform For IoT Applications


MediaTek Labs announced the MediaTek LinkIt Smart 7688 development platform to enable developers and device makers rapidly develop advanced Wi-Fi based devices such as IP cameras, surveillance devices, smart appliances and Wi-Fi gateways that make use of cloud services. The platform running OpenWrt Linux offers a variety of programming options to the developers.

The platform is the latest addition to the LinkIt portfolio of development platforms. Currently, two versions of the platform’s Hardware Development Kit (HDK) are available: the LinkIt Smart 7688, which includes a microprocessor unit (MPU) based on the MediaTek MT7688AN system-on-chip (SOC), and the LinkIt Smart 7688 Duo, which in addition to the MPU includes a microcontroller unit (MCU) and is Arduino compatible. Both development boards feature built-in Wi-Fi, generous 128MB RAM and 32MB Flash, and a wide variety of options for connecting peripherals.

“MediaTek Labs is focused on stimulating innovation in IoT and is pleased to extend its LinkIt family of development platforms to the open-source and web developer communities, enabling broader product development for a more connected world. The new LinkIt Smart 7688 development platform will appeal to a wide range of developers because of its open-source software compatibility, support for several popular programming languages and use of Linux”, said Marc Naddell, VP of MediaTek Labs.


For IoT development, the LinkIt Smart 7688 is said to benefit OpenWrt, Web and mobile app developers, and Arduino communities. Taking advantage of over 2000 software packages with additional functionality, OpenWrt developers can use the standard OpenWrt SDK to create native C applications for their IoT device. Web and mobile app developers can gain support for Node.js and Python. Additionally, Arduino makers can use the popular Arduino IDE to develop applications for the MCU and have realtime control of peripherals.

The MediaTek LinkIt Smart 7688 and 7688 Duo development boards are available to ship globally. A fully open-source version of the Wi-Fi driver is in development and expected to be made available by MediaTek Labs in the coming months.
