ARZ Nexus Shield

All-in-one Arduino learning shield. No wiring. No mess. Real learning.

ARZ Nexus is an educational Arduino shield designed to eliminate breadboards and loose wires while keeping the learning real. It integrates the most commonly used inputs, outputs, and sensors directly on the PCB, so learners focus on logic, code, and system behavior instead of wiring errors.

This is not a toy board and not a black box. Every pin is exposed, labeled, and documented. What you learn here transfers directly to real Arduino projects.

What’s on the shield

• 2 tactile buttons with hardware interrupts

• Potentiometer and LDR for analog input experiments

• Hall-effect sensor

• IR receiver (38 kHz compatible)

• Passive buzzer (PWM)

• RGB LED with individual current limiting

• External PWM LED header

• 3 general-purpose GPIO headers

• Dedicated servo header

• Onboard accelerometer (I2C) with optional interrupt

• UART breakout (RX/TX)

• Power indicator LED

All components are pre-connected to sensible Arduino pins to avoid timer, PWM, and I2C conflicts.
