IBD: Header2 on an Arduino Mega2560R3 - connections


This Internal Block Diagram (IBD) shows Connectors from the 2nd header of the Arduino Mega2560 to pins of the ATmega2560 mcu chip or related nets.

The many Connectors render this large IBD rather cluttered, the idea here in this trail is merely to show how the underlying information can be captured.

Only «pin» Ports on the ATmega2560 mpu chip that have direct connections to «pin» Ports of :Header2 or related nets are shown. In some cases on the board there are actually intermediate nets that are not shown here.

Note how intermediate «node» block instances are used to represent connection via a common «net».

On the Arduino interactive board viewer schematic (SCH) view the pin p99_GND:GND is indicated as AGND.
