Grove - Mega Shield is a extension board for Arduino Mega and Google ADK.
The Grove - Mega Shield is a extension board for Arduino Mega and Google ADK. We have standardized all the connectors into 4 pins (Signal 1, Signal 2, VCC and GND) 2mm connectors and kept some of the 3pin (Signal, VCC and GND ) 2.54mm headers for Servo and Electronic Bricks, which simplifies the wiring of electronics projects. The 4pins buckled connectors also make the wiring situation more stable. The Mega Shield includes Digital 0 - 21 and Analog 0 - 15.
Digital 22 - 53 are NOT implemented.
