1.4.7. Accessories
LinkIt Smart 7688 Duo standard package comes with the development board
only. The accessories are the same as LinkIt Smart 7688. Please refer to
1.3.7”Accessories” for more information.
1.4.8. 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 circled in Figure 7.

2) Next, you will move a resistor by unsoldering and soldering
it to a lower position as shown in Figure 8, after you’re
finished moving the resistor, restart the device and you
should be able to access JTAG mode.
