Arduino Sensor Shield V5.0

KEY FEATURES OF SENSOR SHIELD V5.0:

• This shield brings out the standard Arduino I/O pins to headers along with dedicated ground and power pins per I/O to facilitate connecting sensors other devices.
• The shield also has a number of dedicated connectors that are defined for specific purposes as outlined below, but they can also be considered as general purpose connection points.
• An auxiliary power connector allows separate power to be supplied to the power pins associated with the D0-D13 pins which is handy for driving servo motors.
• A remote reset switch is located on the shield for easy access. It also brings the on-board pin-13 ‘L’ LED up to the shield for easy visibility.

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 Sensor Shield V5 - Power
• VCC = Positive voltage from separate power supply. Typically 5-6V for servos, but can be other voltage as required by the system.
