The Digital Area of Grove - Mega Shield can also be partitioned into four sections according to different function of GPIO:
IIC( 3 connectors ), UART( UART0-3 ), PWM ( PWM2-13 ) and ICSP( not connector ). Please be aware that PWM have two
ways of appearance: 3Pin 2.54mm Header and our standard 4Pin 2mm connector. Those two forms of appearance serve
different purpose, 4Pin 2mm connectors can connect to our standard Groves while 3Pin 2.54mm Header can connect
to Servo, Ultra Sonic range measurement module and Electronic Bricks. Please be aware that When using 3Pin and 4Pin
modules on PWM at the same time, Do take extra attention in case of multi-using the same GPIO. Please refer to the
following diagram:
