Seeeduino Mega ATmega2560 Development Board 16MHz For Arduino
Product Details:
Seeeduino Arduino Mega is a powerful micro-controller derived from Mega. It features ATmega2560 processor which brings a large number of I/O pins, as much as 70 digital I/O, 16 analog inputs, 14 PWM, and 4 hardware serial ports. Compared to Mega, we shrunk the volume of Arduino Mega by at least 30% and made it 100% compatible with Seeed Shield products. And as a member of Seeeduino series, Seeeduino Arduino Mega inherits deliberate details from Seeeduino, like selectable operating voltage(3.3V/5V), right angle reset button, and so on.
Features:
ATmega 2560 @ 16MHz
Selectable 5V/3.3V operation
70 Digital IO
16 Analog inputs
14 PWM outputs
4 Hardware serial ports (UART)
Compatible with most Duemilanove and Diecimila Shields
Small form factor, 30% smaller than Mega
Easy to program, no additional hardware is required to load firmware ?C just plug to a USB port and you??re good to go.
