Arduino UNO R3 board with DIP ATmega328P
The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, 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.

- 96KB of SRAM
- 512KB of flash memory
- Microcontroller : AT91SAM3X8E
- Operating voltage : 3.3V
- DMA Controller
- Input voltage(recommended): 7V – 12V
- Input Voltage (limits): 6-16V
- Digital I/O pins: 54(of which 12 are PWM capable)
- Analog input pins: 12
- Analog outputs pins: 2(DAC)
- Total DC output current on all I/O lines: 130mA
- Total DC current for 3.3V pin : 800mA

- SRAM : 2.5KB
- EEPROM : 1KB
- Clock Speed : 16 MHz
Available for purchase from Amazon India priced a little high at Rs.4616/-
Arduino NANO :
The Arduino Nano is the smallest in the Arduino family and features the same specs as the Arduino Nano. At the heart is the same ATMEGA328P MCU running at 16MHz. What sets this board apart from other Arduino boards is the size. The Nano is very small and is almost the size of a thumb drive. The major difference you see on the board is the missing DC power jack which is present in almost all Arduino boards. Instead of the DC power jack this board derives power from the Micro USB-B connector.
- Microcontroller : ATmega328P
- Operating Voltage : 5V
- Input Voltage (recommended) : 7-12V
- Digital I/O Pins : 22
- PWM Channels: 6
- Analog Input Channels: 8
- DC Current per I/O Pin : 40mA
- Flash Memory: 32KB of which 2KB used by bootloader
- SRAM : 2KB
- EEPROM : 1KB
- Clock Speed : 16 MHz
