In this Post we will learn about Arduino Nano and Arduino uno Pin diagrams and specifies.
Arduino Nano
Arduino nano is a ATmega328 based small and breadboard compatible arduino board. It has mostly same functionality to Arduino Uno but without DC power jack and works with a mini-B USB cable instead of standard one.

Arduino Nano Pin Diagram
- A0 – A7 Analog Pins
- D0 - D13 Digital Pins
- D3,D5,D6,D9,D10,D11 PM
- VIN Voltage input
- GND Ground Pin
- 3v(17) , 5v(27) 3v and 5v Output pins
| Microcontroller | Atmel ATmega168 or ATmega328 |
| Operating Voltage (logic level) | 5 V |
| Input Voltage (recommended) | 7-12 V |
| Input Voltage (limits) | 6-20 V |
| Digital I/O Pins | 14 (of which 6 provide PWM output) |
| Analog Input Pins | 8 |
| DC Current per I/O Pin | 40mA |
| Flash Memory | 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader |
| SRAM | 1 KB (ATmega168) or 2 KB (ATmega328) |
| EEPROM | 512 bytes (ATmega168) or 1 KB (ATmega328) |
| Clock Speed | 16MHz |
| Dimensions | 0.73 x 1.70 |
| Length | 45 mm |
| Width | 18 mm |
| weigth | 5 g |
Arduino Uno
The Arduino Uno is a microcontroller board based on a removable, dual-inline-package (DIP) ATmega328 AVR microcontroller. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs). Programs can be loaded on to it from the easy-to-use Arduino computer program
| Microcontroller | Atmel ATmega32u4 |
| Operating Voltage (logic level) | 5 V |
| Input Voltage (recommended) | 7-12 V |
| Input Voltage (limits) | 6-20 V |
| Digital I/O Pins | 20 (of which 6 provide PWM output) |
| Analog Input Pins | 6 |
| DC Current per I/O Pin | 40mA |
| Flash Memory | 32 KB |
| SRAM | 2.5 KB |
| EEPROM | 1 KB |
| CPU Speed | 16MHz |
- A0 - A5 Analog Inputs
- 0 - 13 Digital Input/Outputs
- 3,5,6,9,10,11 PWM Pins
- 3.3v , 5v 3.3v and 5v out pins
- GND Ground pin
So Other Arduino boards are same like that. I think, This is enough for now and, We will discuss examples from Arduino uno in next Post.
