This is a comparison among Arduino UNO, Arduino Mega, Arduino Nano and Arduino Pro Mini.
1. Introduction:
In this tutorial, we are going to compare Arduino UNO along with Arduino Mega, Arduino Nano and Arduino Pro Mini regarding their processor, speed, I/O pins etc. Lets take a look one by one.
1.1 Arduino UNO:
1. Arduino UNO uses an ATmega328p microcontroller.
2. Operating/Input Voltage: 5V/7-12V.
3. Digital Input/Output Pins/PWM: 14/6 Pins.
4. Analog Input/Output Pins: 6 Pins.
5. 4 Serial Communication Line: D0, D1 Pin.
6. Processing Speed: 16MHz.
7. USB: Regular
8. SRAM[kB]: 2
9. EEPROM[kB]: 1
1.2 Arduino MEGA:
1. Arduino MEGA uses an ATmega2560 microcontroller.
2. Operating/Input Voltage: 5V/7-12V.
3. Digital Input/Output Pins/PWM: 54/15 Pins.
4. Analog Input/Output Pins: 16 Pins.
5. One Serial Communication Line: D0, D1 and D14 to D19 Pins.
6. Processing Speed: 16MHz.
7. USB: Regular
8. SRAM[kB]: 8
9. EEPROM[kB]: 4
1.3 Arduino NANO:
1. Arduino NANO uses an ATmega168/ATmega328p microcontroller.
2. Operating/Input Voltage: 5V/7-9V.
3. Digital Input/Output Pins/PWM: 14/6 Pins.
4. Analog Input/Output Pins: 8 Pins.
5. 1 Serial Communication Line: D0, D1 Pin.
6. Processing Speed: 16MHz.
7. USB: Mini
8. SRAM[kB]: 2
9. EEPROM[kB]: 1
1.4 Arduino PRO MINI:
1. Arduino PRO MINI uses an ATmega328p microcontroller.
2. Operating/Input Voltage: 3.3-5V/3.5-12V.
3. Digital Input/Output Pins/PWM: 14/6 Pins.
4. Analog Input/Output Pins: 6 Pins.
5. 1 Serial Communication Line: D0, D1 Pin.
6. Processing Speed: 8/16MHz.
7. USB: –
8. SRAM[kB]: 2
9. EEPROM[kB]: 1
2. Cost wise Comparison:
The shield which is compatible with Arduino UNO is also compatible with Arduino MEGA, but Arduino MEGA has more I/O Pins then Arduino UNO and also costs more.
Arduino Pro Mini and Arduino Nano are both based on the Uno, except the nano has an FTDI and the mini doesn’t. this makes the mini cheaper and lower power and these are used for smaller scale projects.
For the beginners, Arduino UNO is best for making compact projects with affordable price.
