This is perfectly legal, seeing that the whole Arduino ecosystem is open source! Please note this board is manufactred by Osoyoo! We do have control of the brand and quality of components used! We have also carefully selected suppliers that consistently supply quality products. None of the Arduino Mega2560 R3 boards sold on the internet at this price are original, they are all copies. It is NOT an original Arduino board, but is similar. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Arduino mega 2560 pinout serial#

It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

The Osoyoo Mega2560 Board is fully compatible with Arduino Mega2560 rev.3, it is a microcontroller board based on the ATmega2560. This gives your projects plenty of room and opportunities.” - Overview

With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This is not recommended because you bypass the LD1117S50CTR 5V voltage regulator and have to make sure that the voltage level is stable.“The MEGA 2560 is designed for more complex projects. 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.
