2560 pinout1/14/2024 Flash memory: 256 KB of which 8 KB used by bootloader.Digital I/O pins: 70 (of which 15 provide PWM output).The Mega 2560 R3 works with all existing shields but can work with new shields that use these additional pins. The other is a not connected and is reserved for future purposes. One is the IOREF that is meant to allow shields to adapt to the voltage provided from the board. In addition, there are two new pins placed near the RESET pin. The Arduino Mega revision R3 adds SDA and SCL pins next to the AREF. you can easily make your Arduino wireless with our Wixel shield), making it a great introductory platform for embedded electronics. The Arduino has a large support community and an extensive set of support libraries and hardware add-on “ shields” (e.g. This auxiliary microcontroller has its own USB bootloader, which allows advanced users to reprogram it. Instead, it features an ATmega16U2 programmed as a USB-to-serial converter. The Mega 2560 differs from the preceding Mega in that it does not use the FTDI USB-to-serial driver chip. 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. It has 70 digital input/output pins (of which 15 can be used as PWM outputs and 16 can be used as analog inputs), a 16 MHz resonator, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button. The Arduino Mega 2560, the successor to the Arduino Mega, is a microcontroller board based on a ATmega2560 AVR microcontroller. However, we use and recommend using the normal Arduino IDE from, which is the IDE we ensure our Arduino libraries work with. This is not recommended because you bypass the LD1117S50CTR 5V voltage regulator and have to make sure that the voltage level is stable.Note: This product is manufactured in Italy by affiliates of Arduino Srl, and the product packaging suggests downloading the Arduino IDE from. 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.
