Arduino Proto Shield Rev3
- Arduino 1.0 pin out
- Large 0.1inch prototyping area
- Reset button
- 14pin SMD footprint (50mils pitch)
- 20pin through hole footprint (100mils pitch)
- SPI header
- Long and easy to solder ground/5V rails
Board features as follows:
- 1.0 Arduino pinout
- 1 Reset button
- 1 ICSP connector
- 14 pins SMD footprint (50 mils pitch)
- 32 double row through Hole pads, standard Arduino breakout layout
- Proto aerea with multiple THT pads, 100 mils pitch
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.
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.
On the ICSP connector only 5V, GND and RST are wired to the respective pins on the header. MOSI and MISO are present only on the connector pads.
For more information about the SPI communication see the SPI library.
