Pinout & Header Description:

Digital I/O Headers (D0–D13)

• G = Ground

• V = VCC (Based on SEL jumper selection)

• Signal pins D0–D13

• Includes AREF pin for analog reference voltage

Analog I/O Headers (A0–A5)

• G = Ground

• V = 5V (fixed clean analog voltage)

• Signal pins A0–A5

• Supports use as digital pins if required

Auxiliary Power Screw Terminal

• GND = Ground for external supply

• VCC = External positive supply (5–6V typical for servos)

• Used when SEL jumper is removed

• Prevents power backflow into Arduino 5V line

SD Card / SPI Interface (D10–D13)

• D10 = Chip Select for SD

• D11 = MOSI

• D12 = MISO

• D13 = SCK

• Includes 5V and GND

How to Use:

• Stack the Sensor Shield V5.0 on top of an Arduino Uno or Mega

• Insert sensors, servos, displays, or modules directly into 3-pin headers

• Use SEL jumper to choose:

  • Arduino 5V for simple sensors

  • External supply for power-hungry servos

• When driving servos, supply external 5–6V to the screw terminal

• Do not use external power with SEL jumper installed to avoid damage

• Connect SPI modules through D10–D13 pins on SD header

• Use I2C ports for modules like OLED displays, RTC, BMP sensors

• Use UART header for serial communication modules (GPS, GSM, Bluetooth)
