placa dezvoltare arduino mega 2560 R3 MEGA2560 REV 3 original

Description: Arduino Mega is a microcontroller development board with ATmega2560 as the core. It has 54 groups digital I / O input / output terminal (14 groups do PWM outputs), 16 sets of simulation than the input side, 4 groups UARTs (hardware serial ports), and it use the 16 MHz crystal oscillator. With the bootloader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery. Power supply design: There are two options for the power supply system of the Arduino Mega USB direct power supply or external power supply. The choice of power supply will be switched automatically. External supply AC-to-DC adapter or the battery can be selected on this control panel. Limit the voltage range of 6V ~~ 12V, but if the voltage supplied is less than 6V, I / O port may not be supplied to a voltage of 5V, and therefore instability; If the voltage is greater than 12V, the regulator device may possibly overheating protection, are more likely to damage the Arduino MEGA. Therefore recommended operating supply 6.5 ~ 12V, the recommended power supply to 7.5V or 9V.
