Arduino Mega1280/2560/ADK compatible with Grove interface
Size: 92.8 mm x 57.2 mm
Functional module
Grove-Mega Shield is designed for more convenient connections! Each socket is silk-screened to indicate its pin number. The Grove-Mega Shield mainly has four functional blocks: reset key, analog pin area, digital pin area and power module.
The digital pin area also includes some multiplexed functions: 12C (there are three), hard serial ports (Uart0-Uart3), PWM(PWM2-PWM11), and ICSP. PWM will be output simultaneously at Grove and the Servo interface in the middle. So you should be careful not to use the same pins at the same time to avoid causing some problems.
