As we talked earlier, we have different kinds of Arduino boards with different specifications. These boards extend the area of working with Arduino. For different purposes, different boards are preferred over others and more compatible. We now want to talk about them. In this part, we'll be demonstrating;
-- Arduino Uno
-- Arduino Mega
-- Arduino Due
-- LilyPad Arduino
-- Arduino Leonardo
-- Arduino Nano
-- Arduino Micro
But before that, we need to have some ideas on some terms;
⌕ Flash Memory: It is the program memory of the Arduino where the Arduino sketch is stored.
⌕ SRAM: It stands for Static Random Access Memory. The sketch creates and manipulates variables here when the programs run.
⌕ EEPROM: It is the memory where the programmers store their long-term information.
Now the fact to notice is that Flash memory & EEPROM are non-volatile memories that persist for a long time after the power being off. But the SRAM data is lost when the power is cycled.
▶ Arduino Uno R3 (Revolution 3):
Arduino Uno is the best tool for small projects. It provides a moderate number of input & output pins with compatible specifications. It uses the ATmega 328P onboard chip.

0.5 KB of the Flash Memory is used by the bootloader. We'll get to know more about this board later on.
▶ Arduino Mega:
Mega is called the 'Big Brother' of Uno! Mega offers more input & output pins than Uno and also larger memory components. Usually, Mega is preferred for large projects where many components are needed to be connected with Arduino that Uno can't supply.

▶ Arduino Leonardo:
Leonardo is the first development board of Arduino. It differs from other boards to has a built-in USB communication that doesn't require a secondary processor. Another thing is that the libraries allow the board to act as a keyboard or mouse while connecting to a computer!

This is the most good looking and tiny sized Arduino board. This board is specially modified for e-textile. The purpose of this one is to use wearable clothes. Along with I/O pins, there are board sensors, specially built for e-textiles. The board provides large pin-out holes that made it easy to sew and connect through conductive threads. And will you believe if I say this Arduino is washable !!!
