Arduino Sensor Shield V5 0 Manual ◎

Key Features and Pinout

The Arduino Sensor Shield V5.0 is a versatile expansion board designed to simplify the connection of multiple sensors, servos, and modules to an Arduino Uno or Mega. By breaking out each I/O pin into a 3-pin header (Signal, VCC, Ground), it eliminates the need for messy breadboards and soldering during prototyping.

1. Stacking: Align the pins of the Sensor Shield with the headers on the Arduino Uno. The shield is designed to be "Uno-shaped" and will only fit in one orientation.
2. Press Fit: Gently press the shield down until the pins are fully seated.
3. External Power (Optional): If using high-power devices (servos or motors), connect an external power source to the shield's terminal block, ensuring polarity is correct.

• Blue and Yellow Blocks: These bring out the analog (A0-A5) and digital (D0-D13) pins into standard 3-pin blocks (Signal, Voltage, Ground).
• Servo Connectors: Dedicated 3-pin headers for up to 4 servos.
• I2C Port: A 4-pin connector for OLED displays or I2C real-time clocks.
• Bluetooth/Serial Header: A dedicated spot for HC-05 or HC-06 Bluetooth modules.
• Reset Button: A convenient reset switch on the shield itself.
• Power Indicators: LEDs for 5V and 3.3V rails.

The Arduino's onboard voltage regulator is limited in current (typically 500mA-800mA). If the shield is powered solely via the Arduino's USB connection, driving multiple servos may cause the voltage to drop, leading to a system reset. arduino sensor shield v5 0 manual

Features & Functionality

Now go plug something in. No breadboard required. Key Features and Pinout The Arduino Sensor Shield V5

• The shield does not add pull-up resistors for I2C. It only routes A4/A5.
• If your I2C device lacks pull-ups (e.g., bare OLED), add external 4.7k resistors from SDA to VCC and SCL to VCC.

• SDA (Data Line): Mapped to Analog Pin A4.
• SCL (Clock Line): Mapped to Analog Pin A5.
• This allows for the connection of LCD displays, compass modules, and port expanders using a simple 4-wire cable (VCC, GND, SDA, SCL).

• Digital: D0–D13 — signal pins exposed.
• Analog: A0–A5 — analog inputs exposed.
• PWM: D3, D5, D6, D9, D10, D11 — available for servos/actuators.
• I2C: SDA (A4), SCL (A5) on Uno-compatible shields.
• UART: TX (D1), RX (D0).
• Power rails: +5V, +3.3V selectable; GND common.
