![]() Note: The Arduino Mega 2560 does not include a USB cable, batteries, or a DC power adapter. More information about the Arduino Mega 2560 is available on Arduino’s website. *The Arduino Mega 2560 has 70 total available I/O lines all of them can function as digital I/O lines, and sixteen of them can be used as analog inputs. Flash memory: 256 KB of which 8 KB used by bootloader.Digital I/O pins: 70 (of which 14 provide PWM output) It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a.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. I know this reply is a little late, I had the same problem: interrupts on pin 2, 3, 18 and 19 are no problem, but interrupts on pin 20 (SDA) and 21 (SCL) wont work. Instead, it features the Atmega8U2 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 14 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 rows are not the same, and the end ones are not even the same as each other. The Arduino Mega 2560, the successor to the Arduino Mega, is a microcontroller board based on a ATmega2560 AVR microcontroller. I think, in your case, you can use the pins freely for your purpose but, technically, you are right. Note: This product has been replaced by the newer Arduino Mega 2560 R3. ![]()
