Arduino Proto Shield R3 KIT (unassembled)

by Arduino
Price $ 11.83


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.



Kit Includes:

1 Proto PCB
2 Reset button
1 40x1 single line pinhead connector
1 3x2 dual line pinhead connector
5 220 Ohm Resistors 1/4W
5 1k Ohm Resistors 1/4W
5 10k Ohm Resistors 1/4W
3 5mm LED (Red, Green and Yellow)

Schematic: arduino_ProtoShield_Rev3-schematic.pdf



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


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.
