Summary
A wide prototyping area with some extra features:
| 1.0 | Arduino pinout |
| 1 | Reset button |
| 1 | ICSP connector |
| 14 | pin SMD footprint (50 mils pitch) |
| 20 | pin Through Hole footprint (100 mils pitch) |

Power
The 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.
SPI connection
The ICSP connector available on the shield hove his connections made directly to the SPI pins.
- 1: (the one with the smal pointer sign) MISO connected to D12
- 2: +5V
- 3: SCK connected to D13
- 4: MOSI connected to D11
- 5: SS connected to D10
- 6: GND
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.
