Shield Arduino Mega Pinout Serial Driver Chip
RobotDyn Mega Protoshield are equally sized to Arduino mega 2560 R3 microcontroller board. The Arduino Ethernet has 14 digital input/output pins. This is the same interface found on the Ethernet shield. The Ethernet differs from other boards in that it does not have an onboard USB-to-serial driver chip, but has a Wiznet Ethernet interface. The Arduino Ethernet is a microcontroller board based on the ATmega328.

Three screw holes allow the shield to be attached to a surface or case. Physical CharacteristicsThe maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. Proto aerea with multiple THT pads, 100 mils pitchThe Proto Shield bring the power from the Arduino standard 5V and GND pins to the two power bus rows placed between the Through Hole package footprint, which can be used for powering the DIP sockets, or for power and ground rows. 32 double row through Hole pads, standard Arduino breakout layout
For more information about the SPI communication see the SPI library. MOSI and MISO are present only on the connector pads. SPI ConnectionOn the ICSP connector only 5V, GND and RST are wired to the respective pins on the header.
