Arduino Nano Mega 2560 for Alarm systems
Overview
Emartee Nano Mega 2560 is a microntrolller board, derived from Arduino Mega 2560 with changes in pursuit for small form factor, flexibility and functionality.It has 70 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog 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; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. Emartee Nano Mega 2560 is compatible with most shields designed for the Arduino Duemilanove or Diecimila, also share accessories.
Difference vs. Arduino Mega2560 :
1,Smaller (30% smaller) and flat form factor
2,All IO pin break out.
3,Move Reset button for easy access
4,2.54mm alighment for proto boards compatiblity
5,Selectable 5V/3.3V operation
6,Auto/Manual reset selectable
7,Full featured Uart, Bitbang ready
8,FT232RL VS ATmega8U2
9,16 Analog inputs
10,14 PWM outputs
11,4 Hardware serial ports (UART)
12,Compatible with most Arduino Duemilanove and Diecimila Shields
13,Small form factor, 30% smaller than Arduino Mega
14,Easy to program, no additional hardware is required to load firmware – just plug to a USB port and you’re good to go.
15,ICSP Header
16,Can be powered through a battery or through a AC to DC adaptor

Specification and Comparison :
Schematic
The following diagram illustrates the placement of important integrated circuits, indicator LEDs, connectors common to all Arduino based development platforms and the ones specific to Mega.
NOTES
1,Label [5] The Arduino Nano Mega 2560 uses a 4 Position mini-Type B Jack while the rest of the Arduino family uses standard 4 Position Type B Jack. The Arduino uses circular Power Jack.
2,Label[9] The Arduino Nano Mega 2560 uses a 2 Pin JST connector for the power supply while the rest of the Arduino family uses coaxial power plugs.
3,Label[3] For the Reset button the Arduino Nano Mega 2560 uses a an edge mounted push button while other Arduino based platforms uses a four legged tack switch .
4,Yellow Labels are indicator LEDs.
5,Blue Labels are mode selector and reset switches.
6,Brown Labels are items that are common to the Arduino family; this makes the Arduino Nano Mega 2560 compatible with most Arduino shields.
7,Red Labels are the things that add the Arduino Nano Mega 2560, the set includes additional ADC input pins and a bunch of bidirectional IO pins.
