Key Features
- ATmega328P at 16 MHz: A proven 8-bit AVR core with 32 KB flash, 2 KB SRAM, and 1 KB EEPROM - enough for the vast majority of embedded projects.
- 14 Digital I/O Pins: Six of which support hardware PWM, giving you precise control over motors, LEDs, and servos right out of the box.
- 6 Analog Inputs: 10-bit ADC channels for reading sensors such as temperature probes, potentiometers, light-dependent resistors, and more.
- Dedicated ATmega16U2 USB-to-Serial: Unlike cheaper clones that use CH340 or CP2102 chips, the original Uno Rev3 uses a genuine ATmega16U2 for rock-solid USB communication and native driver support on Windows, macOS, and Linux.
- Flexible Power Options: Power the board via USB, a DC barrel jack (7-12 V recommended), or the VIN pin - the onboard voltage regulator handles the rest.
- Standard Arduino Header Layout: Compatible with hundreds of official and third-party shields - from motor drivers and Ethernet modules to TFT displays and GPS receivers.
- Built-in LED on Pin 13: Instantly verify your board is working with the classic Blink sketch - no external components required.
- ICSP Header: Program the ATmega328P directly via an external programmer, or update the ATmega16U2 firmware for custom USB behaviour.
- Reset Button: Conveniently placed for quick program restarts during development and debugging.
- Overcurrent Protection: A resettable polyfuse on the USB port protects your computer if the board draws excessive current.
Why Choose the Original Over a Clone?
- Genuine ATmega16U2 USB chip: No driver headaches - plug in and start coding on any operating system without installing third-party drivers.
- Consistent, tested components: Every original board passes Arduino's quality control. Clones often use lower-grade capacitors, crystals, and voltage regulators that cause intermittent failures.
- Accurate pin spacing and header alignment: Shields fit perfectly every time. Some clones have slight dimensional errors that make shield stacking unreliable.
- Support the open-source ecosystem: Purchasing an original Arduino directly funds the development of the Arduino IDE, libraries, documentation, and community resources.
- Manufacturer warranty: Covered for 1 full year against defects - something no clone can offer.
Project Ideas
- Home Automation: Control lights, fans, and appliances via relays. Add an ESP8266 Wi-Fi module or Bluetooth HC-05 to enable smartphone control and IoT integration.
- Weather Station: Connect a DHT22 temperature/humidity sensor, BMP280 barometric pressure sensor, and a 16x2 LCD to build a desktop weather monitor with data logging to an SD card.
- Line-Following Robot: Pair the Uno with an L298N motor driver and IR sensor array to build an
