Grove - Mega Shield is an 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 simplify the wiring of electronics projects. The 4-pins buckled connectors also make the wiring situation more stable. The Mega Shield includes Digital 0 - 21 and Analog 0 - 15.
