Arduino Mega Model 2560 R3

A high-performance microcontroller board built on the ATmega2560, featuring extensive I/O options for complex robotics and embedded projects.

Technical Specifications

• Microcontroller: ATmega2560 @ 16 MHz
• Memory: 256 KB Flash (8 KB used by bootloader) | 8 KB SRAM | 4 KB EEPROM
• I/O Pins: 54 Digital I/O (15 PWM outputs) | 16 Analog Inputs
• DC Current Limits: 40 mA per I/O pin | 50 mA for 3.3V pin

Power Supply & Operating Voltage

• Operating Voltage: 5V
• Input Voltage: 7–12V (Recommended) | 6–20V (Limits)
• Power Source Selection: Automatic between USB and external power (DC Jack or VIN).

Power Pins

• VIN: Input for external DC power, or output when powered via DC jack.
• 5V / 3.3V: Regulated power outputs (3.3V max draw: 50 mA). Avoid supplying unregulated power directly to these pins.
• GND: Ground pins.
• IOREF: Voltage reference pin to allow connected shields to adapt to the board's 5V operating level.
