With 54 digital I/O pins, 16 analog inputs, and 4 hardware serial ports, it's the recommended board for 3D printers, robotics, and other complex builds.\n\nThe Rev3 features the ATmega16U2 USB-to-serial converter, the 1.0 pinout with dedicated SDA/SCL and IOREF pins, 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 – 15 usable as PWM outputs\n\n16 Analog Inputs – 10-bit resolution 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\nUSB Overcurrent Protection – Resettable polyfuse protects your computer's USB ports\n\nOpen-Source Hardware – Schematics and Eagle files freely available\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 (15 PWM)\n\nAnalog Input Pins – 16\n\nHardware Serial Ports – 4 UARTs\n\nDC Current per I/O Pin – 20mA (40mA absolute max)\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\nBoard Dimensions – 101.52 × 53.3 mm\n\nWeight – 37g\n\n\nIdeal For\n\n3D printer controller boards\nRobotics with multiple motors and sensors\nLED arrays and multi-sensor setups\nData logging with multiple serial devices\n\n\nPackage Contents\n\n1× Arduino Mega 2560 Rev3\n\n\nResources\n\nSchematic (PDF)\nEagle Design Files\nATmega2560 Datasheet (PDF)\nPin Mapping (ATmega2560)\nArduino Getting Started Guide\nArduino IDE Download\n","vendor":"Pimoroni","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7659,"title":"Default Title","sku":"PI-A000067","price":82.18,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
