LinkIt Connect 7681 - Wi-Fi HDK for IoT

The LinkIt™ Connect 7681 development board provides you with easy access to the five GPIO pins and one UART port — each with an LED — of the MediaTek MT7681 chip, to quickly connect peripheral controllers and electronic circuits. The MT7681 — compact Wi-Fi SoC with embedded TCP/IP stack — is provided on the LinkIt™ Connect 7681 module, co-designed with AcSiP. This module, which is only 15 x 18mm, is also available separately for direct integration into your product’s PCB. (Also see LinkIt™ Connect 7681 module).

The LinkIt™ Connect 7681 development board is part of the LinkIt™ Connect 7681 development platform from MediaTek Labs. This development platform delivers you the tools and documentation to prototype your IoT device and create its final design.
