Description:
The Arduino Mega 2560 R3 is a celebrated open-source microcontroller board, valued for its precision and versatility. Building on the Arduino Mega’s legacy, it employs the ATmega2560 SMD chip. Enhancements include:
- SDA and SCL pins next to the AREF pin
- Two additional pins by the RESET pin
- The IOREF pin allows shields to match the board’s voltage
- Another reserved pin provided for future upgrades
- With 54 digital input/output pins (15 supporting PWM output), 16 analog inputs, and 4 UARTs (hardware serial ports), the Mega 2560 R3 boasts a wide array of connectivity options. It also features:
- 16 MHz crystal oscillator
- USB connection
- Power jack
- ICSP header
- Reset button
Offering full support for the microcontroller.
Designed for ease of use, the board can be connected to a computer via a USB cable or powered by a DC adapter or battery. Its compatibility with existing shields and ability to adapt to new ones render it an ideal choice for diverse projects and applications.
