🇮🇹 Official Arduino Product (Made in Italy)
You are viewing the authentic Arduino Uno R3. Unlike cheaper clones, this board uses high-quality components and supports the original creators of Arduino.
The Official Arduino UNO R3 is the world’s most trusted beginner and prototyping board. Powered by the ATmega328P @ 16 MHz, it combines 14 digital I/O (6 PWM), 6 analog inputs, rock-solid 5V logic, and the broadest ecosystem of Arduino shields, sensors, and displays.
If you’re teaching a class, starting a professional lab, or bootstrapping a product idea in the Philippines, this is the reliable choice.
Why Buy the Official Board? (vs. Clones)
- Plug & Play Reliability: Uses the genuine ATmega16U2 USB chip. No need to hunt for "CH340" drivers or deal with connection dropouts.
- Industrial Quality: Manufactured in Italy with high-grade PCBs that withstand repeated soldering and classroom abuse.
- Support Open Source: A portion of your purchase funds the development of the Arduino IDE and new libraries you use every day.
What You Can Build
- STEM Projects: Traffic light controllers, automated temperature loggers, distance meters.
- Home Automation: Smart plant watering systems (relay + soil sensor), motion-activated alarms (PIR).
- Robotics: Line followers and 2WD cars using motor shields and IMU sensors.
Starter Bundles (Quick Picks)
- UNO Learning Kit: UNO R3 + USB-B cable + breadboard & jumpers + basic sensors + 0.96″ OLED
- Sensor Lab: UNO R3 + BME280 + HC-SR04 + relay + data logging shield
- Robot Starter: UNO R3 + 2WD chassis + L293D shield + battery/PSU
⚠️ Essential Add-Ons (Not Included in Box)
Note: The official box does not include a USB cable.
- Add a USB-B Cable here (Required for programming)
Other Recommended Parts:
- Sensor packs (DHT22, PIR, HC-SR04, IMU, light)
- Displays (1602 LCD, OLED, TFT)
- 9V/12V Power Supply & Barrel Jack Adapter (For standalone power)
- Protective Cases (Clear acrylic, ABS)
