Each pin includes dedicated VCC and Ground pins for "plug-and-play" sensor or servo attachment.

If you have ever tried to connect multiple sensors (like an Ultrasonic sensor, a Servo motor, and a Gas sensor) directly to your Arduino Uno, you know the struggle: tangled wires, loose jumper connections, and the constant fear of plugging something into the wrong pin. The is the definitive solution to this prototyping nightmare. arduino sensor shield v5 0 manual
The beauty of the v5.0 is that you rarely need a breadboard anymore.
| Interface | Pins | Use Case | |-----------|---------------------------------|---------------------------| | I2C | SDA (A4), SCL (A5), +5V, GND | OLED, BMP280, RTC modules | | UART | RX (D0), TX (D1), +5V, GND | Bluetooth (HC-05), GPS | | SPI | ICSP header (physical 2x3 pins) | SD card, RF modules | Each pin includes dedicated VCC and Ground pins
This is the shield’s magic.
Plug the standard 3-wire servo connector directly into a digital pin row (e.g., ). Ensure the brown/black wire aligns with G , red aligns with V , and yellow/orange aligns with S . 5. Troubleshooting and Best Practices If you share with third parties, their policies apply
The "V" pins on the digital rails are disconnected from the Arduino's 5V supply. Power must be supplied through the external blue terminal block. Always remove this jumper if driving multiple servos to avoid frying your Arduino. Bluetooth / APC220 Interface
: Dedicated ports for specific modules, including: I2C (IIC) : 4-pin header for SCL, SDA, 5V, and GND. SPI : Header for SD card or wireless interfaces. Serial (COM) : For Bluetooth or APC220 wireless modules. LCD : Supports both parallel and serial LCD connections.
The is an expansion board designed to simplify connections between Arduino (Uno R3, Leonardo, or compatible boards) and various sensors, servos, and communication modules. Instead of messy breadboard jumper wires, this shield provides labeled, standardized interfaces (3-pin, 4-pin, I2C, Serial, etc.).
