The A000067 is a Arduino Mega2560 Rev3 development board based on ATmega2560 microcontroller. The board has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller, simply connect it to a computer with a USB cable or power it with a AC to DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Uno, Duemilanove or Diecimila. The Arduino Mega can be powered via the USB connection or with an external power supply. The power source is selected automatically. The Arduino Mega2560 has a number of facilities for communicating with a computer, another Arduino or other microcontrollers.
ATmega16U2 instead 8U2 as USB to serial converter
1.0 pinout
Stronger RESET circuit
5V operating voltage
Input voltage (recommended) range from 7V to 12V
Input voltage (limit) range from 6V to 20V
40mA DC current per I/O pin
256KB flash memory of which 8KB used by bootloader
8KB SRAM
4KB EEPROM
The recommended range is 7V to 12V, if using more than 12V, the voltage regulator may overheat and damage the board.
