Arduino Uno R3 Compatible Board — ATmega328P + ATmega16U2 USB
This Arduino Uno R3 compatible board uses the same ATmega16U2 USB-to-serial chip as the official Arduino Uno R3 — providing maximum driver compatibility and reliable USB communication on Windows, Mac, and Linux without additional driver installation. Built around the ATmega328P microcontroller with 14 digital I/O pins, 6 PWM outputs, and 6 analog inputs. Compatible with all Arduino Uno R3 shields and the full Arduino IDE library ecosystem.
Hardware Specifications
- MCU: ATmega328P @ 16MHz
- Flash: 32KB (0.5KB used by bootloader)
- SRAM: 2KB | EEPROM: 1KB
- Digital I/O: 14 pins (6 PWM capable)
- Analog Inputs: 6 channels (10-bit ADC)
- Interfaces: UART, SPI, I²C
- USB Chip: ATmega16U2 (same as official Arduino Uno R3)
- USB Connector: USB-B
- Operating Voltage: 5V
- Input Voltage: 7–12V (DC jack) or 5V (USB)
- IDE: Arduino IDE compatible
ATmega16U2 vs CH340 — Which USB Chip?
- ATmega16U2 (this board): Same chip as official Arduino Uno R3 — no driver needed on most systems, maximum compatibility, can be reprogrammed as HID device
- CH340: Requires CH340 driver installation on Windows — lower cost alternative
- Choose ATmega16U2 for maximum compatibility and official Arduino experience
Typical Applications
- Arduino learning and beginner projects
- Sensor reading and data logging
- Motor and servo control with Arduino shields
- Home automation and IoT prototyping
- Arduino shield development and testing
Arduino Uno R3 compatible with ATmega16U2 USB — maximum driver compatibility, full shield support, Arduino IDE plug-and-play for beginners and professionals.
