V4.0 Sensor Shield

The V4.0 Sensor Shield is an expansion board that plugs on top of an Arduino Uno and turns the I/O pins into 3-pin headers with ground, power and signal side by side. Sensors, servo motors and modules then connect with a single 3-wire cable, without a breadboard and without running separate power and ground wires. It is a quick way to build robots and multi-sensor projects in class or at home.

V4.0 Sensor Shield Specifications

• Compatible boards: Arduino Uno and boards with the same standard header layout
• Digital I/O: digital pins broken out as 3-pin headers (GND, VCC, signal)
• Analog inputs: A0–A5 broken out as 3-pin headers (GND, VCC, signal)
• Communication port: 4-pin connector that can be set to I2C or UART with jumpers
• Header pitch: 2.54 mm, fits Dupont and standard servo connectors
• Mounting: stacks directly on the Arduino headers

V4.0 Sensor Shield Applications

• Robots and robotic arms with several servos
• Projects that combine many sensor modules
• STEM classes and workshops where wiring must be quick and tidy
• Fast prototyping with plug-in sensor modules

What's in the Box

• 1 × V4.0 sensor shield (Arduino board not included)

Tip: Match the cable colours to the GND, VCC and signal pins before plugging in a module, because a reversed connector can damage it. Several servos together can draw more current than the Arduino's 5 V pin can supply, so power large servo setups from a separate supply with a shared ground.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
