Additionally, the board's large number of digital and analog input/output pins, as well as its support for multiple hardware serial ports, makes it well-suited for projects that require a high level of connectivity.Īrduino Mega 2560 Rev3 Pin Headers and Components The Arduino Mega 2560 Rev3 is compatible with most shields designed for the Arduino Duemilanove or Diecimila, making it a versatile option for expanding the capabilities of the board. ICSP header for programming with an external programmer.Power jack for an external power source.USB Type B connection for programming and power.54 digital input/output pins (of which 14 can be used as PWM outputs).It was first released in 2010 and has since become a popular choice among makers, hobbyists, students, and professionals in the fields of engineering, robotics, and electronics. This is not recommended because you bypass the LD1117S50CTR 5V voltage regulator and have to make sure that the voltage level is stable.The Arduino Mega 2560 Rev3 is a microcontroller board based on the ATmega2560. You can also power power the Arduino microcontroller from the 5V pin. You cannot power the board with the barrel jack and VIN GPIO at the same time, because there is a polarity protection diode, connecting between the positive of the barrel jack to the VIN pin, rated at 1A. Therefore you are able to power the Uno with an external 9 Volt battery. The voltage has to be between 7V and 12V.

VIN Pin: If you use an external power supply like a battery, you can use the VIN pin.If you buy a DC power jack, make sure the power adapter of the plug supplies a voltage between 7V and 12V. DC Power Jack: It is possible to use the DC power Jack as power supply.

The standard USB connection delivers 5V and allows you to draw 500mA in total.

USB cable: The most popular and also the easiest way to power the microcontroller is via USB cable.

Like the Arduino Uno, you can power your Arduino Mega in three save ways because a voltage regulator provides a regulated and stable voltage for the ATmega2560 microprocessor: In my opinion you should be save to draw a current up to 100mA. The LP2985-33DBVR has a maximum output current of 150mA but on the official Arduino website, the maximum current is limited to 50mA. The maximum current draw from the USB connection is therefore reduced to 500mA.īecause the Arduino Mega has 3.3V pins to supply external electrical devices, there is a second voltage regulator build in, that reduces the voltage from 5V to 3.3V.

There is no need for a voltage regulator because the USB connection is already regulated by the USB output from your PC or laptop. The Arduino Mega can also be powered via the USB port.

The maximum output current of the LD1117S50CTR is 800mA. Besides a higher input voltage than 12V has no advantage. But an input voltage between 7V and 12V is recommended to use the Arduino Mega over an extended period of time because otherwise the voltage regulator produces a lot of heat that can damage the microcontroller. The LD1117S50CTR provides a stable 5V output for the ATmega2560 and has a maximum input voltage of 15V.
