OSH: Schematics
Arduino Proto Shield is open-source hardware! You can build your own board using the following files:

Power
The Proto Shield bring the power from the Arduino standard IOREF and GND pins to the two power bus rows
placed between the Through Hole prototyping are, which can be used for powering correctly your project
independently on the chosen board (3V3 or 5V).
SPI Connection
On the ICSP connector only 5V and GND are wired to the respective pins on the header. MOSI and MISO
are present only on the connector and on the near extra pads.
For more information about the SPI communication see the SPI library.
Physical Characteristics
The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. Three screw
holes allow the shield to be attached to a surface or case. Note that the distance between digital pins 7 and 8
is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.
