Arduino UNO Proto Shield (Rev. 3)The Arduino Prototyping Shield makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard (not included) to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino I/O pins, and it's got space to mount through-hole and surface mount integrated circuits. It's a convenient way to make your custom circuit and Arduino into a single module.
SummaryA wide prototyping area with some extra features:
- 1.0 Arduino pinout
- 1: (the one with the small 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 CharacteristicsThe 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.
