Grove Breakout for LinkIt Smart 7688 Duo
This expansion board adds a Grove unified socket to the LinkIt Smart 7688 Duo development platform. It simplifies wiring so that beginners and rapid-prototyping teams can connect sensors and actuators without soldering. The board targets IoT gateway, robotics, smart-multimedia and educational projects.
Build integration
The breakout mounts directly onto the LinkIt Smart 7688 Duo, exposing I2C and UART buses plus reserved original pins. It draws 5.0 V from the USB power port and regulates to 3.3 V for attached modules. No battery is included, so a USB supply must be present. The 135mm x 65mm x 34mm footprint and 45 g weight fit inside compact enclosures.
Capacity and headroom
The board provides one Grove connector per bus, so a single I2C or UART device can be attached at a time. It handles the 3.3 V logic levels of the MT7688 and ATmega32u4 without level-shifting circuitry. Projects that require multiple simultaneous Grove sensors or higher current loads will need additional expansion.

Questions about this item
What is the maximum sustained input voltage the Grove Breakout for LinkIt Smart 7688 Duo can handle during long sessions?
The board accepts a steady 5.0 V through its USB power port and regulates it down to 3.3 V for the onboard circuitry.
How much heat or noise does the breakout produce when it runs continuously?
The board has no active cooling or moving parts, so it generates no audible noise and only minimal warmth from the voltage regulator.
Which development board must I already own for this breakout to work?
You need a LinkIt Smart 7688 Duo development board; the breakout plugs directly into its headers and exposes I2C, UART and reserved pins.
