MAKEVMA101
The MAKEVMA101 (Arduino
®
compatible) Mega 2560 is a microcontroller board based on the ATmega2560. It
has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analogue inputs, 4 UARTs
(hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a
reset button. It contains everything needed to support the microcontroller. Connect it to a computer with a
USB cable or power it with an AC-to-DC adapter or battery to get started. The Mega is compatible with most
shields designed for the Arduino
®
Duemilanove or Diecimila.
