Arduino Mega 2560 R3 Compatible Board with ATmega16U2 USB

Arduino Mega 2560 R3 Compatible Board with ATmega16U2 USB

The Arduino Mega 2560 R3 compatible board is the standard high-I/O Arduino board, built around the ATmega2560 with 54 digital I/O pins, 16 PWM outputs, 16 analog inputs, and 4 hardware UART ports. Uses the ATmega16U2 for USB-to-serial conversion — the same chip as the official Arduino Mega R3, providing reliable USB communication and compatibility with all official Arduino drivers.

Key Specifications

• MCU: ATmega2560 | Clock: 16MHz
• Flash: 256KB | SRAM: 8KB | EEPROM: 4KB
• Digital I/O: 54 pins | PWM: 15 channels | Analog in: 16 channels
• UART: 4 hardware serial ports | Interfaces: SPI / I2C
• USB: USB-B (ATmega16U2) | IDE: Arduino IDE compatible
• Compliance: RoHS compliant

Why Choose This?

• ✅ ATmega16U2 USB chip — same as official Arduino Mega R3, maximum driver compatibility
