Arduino Sensor Shield V4.0 Expansion Board for Uno - Easy Prototyping
Arduino Sensor Shield V4.0 – Expand Your Uno with Easy Sensor Connections
The Arduino Sensor Shield V4.0 is an expansion board designed to stack directly onto an Arduino Uno. It breaks out all I/O pins into organized 3-pin headers, enabling quick and solderless connections for sensors, servos, and modules. Ideal for rapid prototyping, it simplifies wiring and reduces clutter in your projects.

Compatibility
This shield is designed for the Arduino Uno R3 form factor. It can also work with Arduino Mega 2560 if aligned correctly, but check pin mapping for compatibility. All pins operate at 5V logic; use level shifters for 3.3V sensors if needed. Common pairings include HC-SR04 ultrasonic sensors, DHT11/DHT22 temperature sensors, and servo motors.
Wiring Notes
Simply align the male headers with your Arduino Uno and press firmly. All signal, power, and ground connections are pre-routed to the 3-pin headers; no additional wiring is needed for most sensors. If using high-current loads like multiple servos, power them through the shield’s separate power input header rather than the Arduino’s 5V pin.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this shield compatible with the Arduino Mega?
Yes, it can physically stack on the Mega, but some pins (like I2C) are on different locations. You will need to adjust the wiring in your code accordingly.
Can I use this shield with a Raspberry Pi?
No, this shield is designed for 5V Arduino boards and does not match the Raspberry Pi’s GPIO header or 3.3V logic. You would need a separate adapter.
Do I need to solder anything?
The shield comes with pre-soldered headers for stacking onto the Arduino. The sensor pins are typically male headers, so you will connect sensors using jumper wires without soldering.
