Key Features
- 100% Genuine Arduino Board: Official product manufactured in Italy with the Arduino logo, holographic sticker, and unique serial number - not a clone or counterfeit.
- SMD ATmega328P: Surface-mount version of the proven ATmega328P microcontroller offers the same performance as the DIP variant while providing a more compact, robust solder connection.
- ATmega16U2 USB-to-Serial: Dedicated USB interface chip provides reliable, fast communication and allows the board to appear as a virtual COM port, mouse, keyboard, or MIDI device with custom firmware.
- Plug-and-Play with Arduino IDE: Simply connect via USB Type-B cable, open the free Arduino IDE, select "Arduino Uno," and start uploading sketches immediately - no additional drivers required on most operating systems.
- 14 Digital I/O Pins (6 PWM): Control LEDs, relays, motors, servos, buzzers, and more. Six pins support hardware PWM for smooth dimming, speed control, and analog-like output.
- 6 Analog Input Pins: Read data from sensors such as temperature, light, humidity, potentiometers, and flex sensors with 10-bit ADC resolution (0-1023).
- Multiple Communication Protocols: Built-in UART (serial), SPI, and I2C (TWI) let you interface with displays, SD cards, GPS modules, Bluetooth/Wi-Fi modules, RTCs, and hundreds of other peripher
