Arduino Mega 2560 R3 Board

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 and two additional pins by the RESET pin. The IOREF pin allows shields to match the board’s voltage, and another reserved pin is 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 a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button, offering full support for the microcontroller.
