WHAT AND WHYS???

What runs in so many minds while purchasing Arduino boards for their first time  is, “what arduino board should i buy and why?” We here for you don’t you worry… by the time you are done reading through this page you will be way wiser and up for the task

To start of you need to have a list of “whys and whats” you need, to achieve your purpose.

Things to consider are;

  • Functionality-Operation,what workload can the board handle,memory size
  • Design- Size(the physical size of the board), ports, features just to mention a few
  • Cost- The pricing in relation to your budget, function and design

On our blog we shall discuss the most common boards Arduino UNO,MEGA,NANO, PRO-MINI and finally PRO-MICRO differences (this should help in making a wise decision on the board to buy)

below are interesting shallow tips 

  • The Arduino Uno is the old,Loyal and sweet workhorse that everyone loves and relates to because it’s cost, availability,functionality and design favors beginners and somehow it has lots of support documents on internet
  • The Arduino Mega – the Papa Bear with more I/O ports than you’ll know what to do with (Its a supplement of the Uno board)
  •  The Arduino Nano -Its a powerful board in a small package, very good while using the breadboard it fits perfectly on the breadboard
  • The Arduino Pro-Mini – Another great option when you don’t need a USB port, it’s really tiny in a nice way makes the project compact and reasonably small (here you The Guru hamna wasiwasi at all)
  • The Arduino Pro-Micro- Same size as a pro-mini and has a usb port but different micro controller

  • Difference between Arduino UNO and Arduino Nan

The Arduino Nano is very much similar to the Arduino UNO. They use the same Processor (Atmega328p) and hence they both can share the same program. One big difference between both is the size UNO is twice as big as Nano and hence occupies more space on your project. Also Nano is breadboard friendly while Uno is not. To program a Uno you need Regular USB cable where as for Nano you will need a mini USB cable. The technical difference between Uno and Nano is shown below.

  • Difference between Arduino Nano and Arduino Mega

There is a considerable amount of difference between the Arduino Nano and the Arduino mega as the processor used itself is different. Arduino Mega is more powerful than an Arduino Nano in terms of speed and number of I/O pins. As you might guess the size is also bigger than an Arduino UNO. Arduino Mega is normally used for projects which require a lot of I/O pins and different Communication protocols. The technical difference between Nano and Mega is shown below.

  • Difference between Arduino Pro mini and Arduino Pro micro

Apart from the minor pin differences, the peripherals for both MCUs are the same. The major difference is the ATMega32u4 has built in full-speed USB. This allows the board to function as a USB device by implementing the appropriate USB stack. Additional differences are the ATMega32u4 uses more power than the ATMega328P and to wind it up ATMega32u4 has 5 available true hardware interrupts (so-called “external”), whereas ATMega328p only has 2. for technical differences see the table shown below
