Arduino Sensor Shield V5.0 Go to product viewer dialog for this item.
is an expansion board that stacks directly onto an Arduino Uno to simplify sensor and servo connections by breaking out each I/O pin into a dedicated 3-pin header (Signal, VCC, GND). 1. Physical Layout & Pinout
The shield organizes pins into specialized blocks, allowing for "plug and play" connectivity without a breadboard.
Digital I/O Block (D0–D13): Each pin consists of three vertical headers: S (Signal): Connected to the Arduino digital pin. V (VCC): Positive power supply (usually 5V). G (GND): Ground (0V).
Analog Input Block (A0–A5): Also broken out into 3-pin G-V-S headers for analog sensors like potentiometers or temperature sensors. Dedicated Interfaces: arduino sensor shield v5 0 manual
IIC (I2C): 4-pin header (GND, VCC, SDA, SCL) for I2C devices.
COM (UART): 4-pin header (GND, VCC, TX, RX) for Bluetooth (e.g., HC-05) or GPS. SD Card: Dedicated header for SPI-based SD card modules. APC220: Wireless RF communication interface. Ultrasonic: Port labeled "URF" for HC-SR04 sensors. LCD: Interfaces for both serial and parallel 128x64 LCDs. 2. Power Management & SEL Jumper
This shield is unique because it can isolate high-current devices (like servos) from the Arduino's delicate 5V regulator. Arduino Sensor Shield V5: Easy Connections Guide - PCBSync
The shield provides a dedicated 4-pin header for I2C communication. Arduino Sensor Shield V5
Q: Does this work with Arduino Mega 2560? A: Partially. The first 14 digital pins and first 6 analog pins line up, but the rest of the Mega’s pins will hang off the edge. You can use it, but you lose pins D14-D53.
Q: Can I use 5V and 3.3V sensors interchangeably? A: The shield only outputs 5V (unless you change the jumper to external and supply 3.3V externally, which is risky). For 3.3V sensors (like the HCSR-04 ultrasonic), use a level shifter between the sensor and the shield.
Q: Why is there a "Blue" and "Yellow" area? A: Aesthetics only. Historically, blue indicates analog signals, yellow indicates digital, but electrically they are identical.
Q: My shield didn't come with headers. A: Some clones are sold as "kit only." You need to solder standard 8-pin and 6-pin stackable headers yourself. Use a vice to hold the headers straight while soldering. SDA (Data Line): Mapped to Analog Pin A4
| Function Block | Connector Label | Arduino Pin | Signal Type |
| :--- | :--- | :--- | :--- |
| Analog (Blue) | A0 – A5 | A0 – A5 | Analog Input / Digital |
| Digital (Black) | D0 – D13 | 0 – 13 | Digital I/O |
| PWM (~) | D3, D5, D6, D9, D10, D11 | Same | Hardware PWM |
| Servo Ports | Row of 3-pins (G/V/S) | D9, D10, D11, D12 | Signal for Servo control |
| I2C | 4-pin block | A4 (SDA), A5 (SCL) | I2C Data/Clock |
| Serial (UART) | D0 (RX), D1 (TX) | 0 (RX), 1 (TX) | Do not use if uploading code |
| SPI | ICSP header (duplicated) | D13(SCK), D12(MISO), D11(MOSI), D10(SS) | High-speed SPI |
| External Power | EXT_PWR screw terminal | None | Powers shield only (7-12V DC) |
Think of it as a "breakout board for breakout boards." Instead of plugging your sensors (like a PIR motion sensor, ultrasonic sensor, or servo) directly into the Uno’s messy headers, you plug them into the shield. The shield stacks directly on top of your Arduino Uno.
