Sensor Shield V5
Compatible with Arduino boards Uno, Mega 2560, etc.
Board size: 57 x 57 mm
Power System
One of the benefits of this shield is that it brings each of the standard Arduino I/O pins out to 3-pin headers along with a dedicated Ground and Vcc pin.
The VCC pins associated with A0-A5 as well as the misc I/O connectors are all hardwired to the Arduino 5V power. Sensors generally need as clean of power as possible, so keeping these on the Arduino 5V makes sense.
The VCC pins associated with D0-D13 are controlled by the SEL jumper.
SEL jumper installed = The Arduino 5V power is connected to these pins as well. This mode facilitates using digital sensors and other low power I/O.
SEL jumper removed = The Arduino 5V power is removed and the power for the pins must be supplied by a separate power supply connected to the 2-pos screw terminal. This is commonly used when servo motors are being driven so that they can be powered from a separate power supply since they exceed the current capability of the built-in 5V and the servo motors create too much electrical noise back into the Arduino electrical system.
2-Pos Screw Terminal
GND = Ground for separate power supply
VCC = Positive voltage from separate power supply. Typically 5-6V for servos, but can be other voltage as required by the system.
Note: With the SEL jumper installed, there must not be external power applied to the 2-pos screw terminal or damage may result since it will short the external and on-board power systems together.
Digital I/O Headers
This group of headers simply brings out the D0 thru D13 Digital I/O lines and couples them with a dedicated ground and VCC pin. The SEL jumper determines the power that is supplied to the VCC pins as noted above.
3 x 16 Header
G = Ground
V = Vcc (Source determined by SEL jumper)
0 – 13 = Digital I/O lines D0 thru D13
Also note that AREF is brought on this line of headers. AREF is the analog reference voltage for the Arduino ADC.
Analog I/O Headers
This group of headers simply brings out the A0 thru A5 Analog I/O lines and couples them with a dedicated ground and VCC pin. The analog inputs can also be used as additional digital I/O lines.

V = 5V
A0-A5 = Analog inputs A0 thru A5
SD (SD Card Interface)
This header provides the three SPI data lines on D11-D13 as well as D10 for an SD Card Select line and power and ground. Originally designed to interface to SD memory cards but can be used to connect to any SPI device.
