Ch340 Arduino Mega 2560 With Cable Printer It is compatible with low-voltageWell, Arduino UNO is known as the most popular Arduino board, and follow behind is is Arduino Mega. The reasons are: 5V powered and operated, as Arduino UNO too and a lot of interface, sensors, output devices are still 5V. 54 digital IO pins versus 14 digital IO pins on UNO, there are 40 extra digital IO pin compared to Arduino UNO :) 15 PWM pins versus 6 only on UNO, 9 extra on Mega :) 16 Analog inputs versus 6 only analog inputs on UNO. 256KByte of
