Arduino Mega 2560 Rev3
48 units available with a short lead time.
The Arduino Mega 2560 Rev3 is a microcontroller board based on the ATmega2560, offering significantly more I/O than standard Arduino boards. With 54 digital I/O pins, 16 analog inputs, and 4 hardware serial ports, it's the go-to board for complex projects that demand extensive connectivity.
The Rev3 update introduces the ATmega16U2 USB-to-serial converter (replacing the 8U2), the 1.0 pinout with dedicated SDA/SCL pins and IOREF for improved shield compatibility, and a stronger reset circuit. Compatible with most shields designed for the Arduino Uno, Duemilanove, and Diecimila.
