{"title":"Arduino Mega 2560 Rev3","handle":"arduino-mega-2560-rev3","url":"/products/arduino-mega-2560-rev3","description":"The Arduino Mega 2560 Rev3 is a microcontroller board based on the ATmega2560, offering significantly more I/O than standard Arduino boards. With 54 digital I/O pins, 16 analog inputs, and 4 hardware serial ports, it's the go-to board for complex projects that demand extensive connectivity.\n\nThe Rev3 update introduces the ATmega16U2 USB-to-serial converter (replacing the 8U2), the 1.0 pinout with dedicated SDA/SCL pins and IOREF for improved shield compatibility, and a stronger reset circuit. Compatible with most shields designed for the Arduino Uno, Duemilanove, and Diecimila.\n\nKey Features\n\n\n54 Digital I/O Pins – 14 usable as PWM outputs\n\n16 Analog Inputs – For extensive sensor arrays\n\n4 Hardware UARTs – Multiple serial connections for GPS, Bluetooth, and other modules\n\n256KB Flash Memory – Room for large, complex sketches (8KB used by bootloader)\n\nRev3 Pinout – SDA/SCL and IOREF pins, ATmega16U2 USB-to-serial converter\n\nBroad Shield Compatibility – Works with most existing Arduino shields\n\n\nSpecifications\n\n\nMicrocontroller – ATmega2560\n\nOperating Voltage – 5V\n\nInput Voltage – 7–12V recommended (6–20V limits)\n\nDigital I/O Pins – 54 (14 PWM)\n\nAnalog Input Pins – 16\n\nHardware Serial Ports – 4 UARTs\n\nDC Current per I/O Pin – 40mA\n\nDC Current for 3.3V Pin – 50mA\n\nFlash Memory – 256KB (8KB used by bootloader)\n\nSRAM – 8KB\n\nEEPROM – 4KB\n\nClock Speed – 16MHz\n\n\nIdeal For\n\nProjects requiring many I/O pins (LED arrays, multi-sensor setups)\nRobotics with multiple motors and sensors\n3D printer controller boards\nData logging with multiple serial devices\n\n\nPackage Contents\n\n1× Arduino Mega 2560 Rev3\n\n\nResources\n\nSchematic (PDF)\nATmega2560 Datasheet (PDF)\nArduino IDE Download\nArduino Getting Started Guide\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9373,"title":"Default Title","sku":"DF-DFR0108","price":119.5,"on_sale":false,"in_stock":true,"available_quantity":99,"option1":"Default Title"}]}
