Breakout Board
A breakout board for LinkIt Smart 7688 development boards is available from Seeed Studio. This
breakout board provides all the pin-outs from the MT7688 and ATmega32U4 which allow you to
connect sensors and peripherals easily.

JTAG
You can use JTAG interface to debug MT7688AN. To access JTAG interface, you will need to
unsolder resistor R95 and solder it to resistor R3 on the 7688 development board. After you’ve
moved the resistor and reboot the device you’ll activate JTAG function. The steps are:
1)
Find a group of resistors on the bottom side of LinkIt Smart 7688 Duo (top-right view) as
