Arduino Mega Shield for Grove Sensors

The Grove Mega Shield v1.2 is an extension board designed for Arduino Mega 1280 and 2560 boards. It standardises connections using 4-pin 2 mm buckled connectors for Grove modules and retains 3-pin 2.54 mm headers for servos and Electronic Bricks. The shield breaks out Digital 0 to 21 and Analog 0 to 15.

Suits Grove-based prototyping; not for full Mega I/O

This shield suits builders who want to connect Grove sensors, actuators and modules to an Arduino Mega without soldering or jumper wires. It is not for projects that require access to Digital pins 22 to 53, as those are omitted to maintain compatibility with the Xduino Mega and Google ADK form factor.

Digital pins 0-21 and Analog 0-15 only

The decisive specification is the I/O range: the board provides Digital 0 to 21 and Analog 0 to 15. Pins 22 to 53 are not broken out, so any design needing those higher digital pins cannot use this shield. Dimensions are 92.8 mm by 57.2 mm.

Questions about this item

Will this Grove Mega Shield v1.2 fit my Arduino Mega 2560 board?

Yes, the shield is compatible with Arduino Mega 1280 and 2560 boards and aligns with their pin headers for direct mounting.

Can I still use the higher digital pins 22 to 53 on my Mega while this shield is attached?

The shield abandons digital pins 22 through 53 to ensure easy installation with Xduino Mega and Google ADK, so those pins remain unused by the shield.

How can I verify the Grove Mega Shield v1.2 is working after I connect it?

Connect a Grove sensor to one of the 4-pin ports, upload a sketch that reads the corresponding digital or analog pin, and confirm the serial output changes as expected.
