It is the first board based on a 32-bit ARM core microcontroller. It has 54 digital input \/ output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. \u003cbr\u003e\n \u003cbr\u003e\nThe board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. The Due is compatible with all shields that work at 3.3V and are compliant with the 1.0 pinout. \u003cbr\u003e\n \u003cbr\u003e\nThe SAM3X has 512KB (2 blocks of 256KB) of flash memory for storing code. The bootloader is preburned in factory and is stored in a dedicated ROM memory. The available SRAM is 96KB in two contiguous bank of 64KB and 32KB. All the available memory (Flash, RAM and ROM) can be accessed directly as a flat addressing space. \u003cbr\u003e\n \u003cbr\u003e\nIt is possible to erase the Flash memory of the SAM3X with the onboard erase button. This will remove the currently loaded sketch from the MCU. To erase, press and hold the Erase button for a few seconds while the board is powered. \u003cbr\u003e\n \u003cbr\u003e\nFeature: \u003cbr\u003e\nThe Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are: \u003cbr\u003e\n \u003cbr\u003e\nA 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock. \u003cbr\u003e\nCPU clock at 84Mhz. \u003cbr\u003e\n96KBytes of SRAM. \u003cbr\u003e\n512KBytes of flash memory for code. \u003cbr\u003e\nA DMA controller, that can relieve the CPU from doing memory intensive tasks. \u003cbr\u003e\n \u003cbr\u003e\nWarning: \u003cbr\u003e\nUnlike other boards, the Due board runs at 3.3V. The maximum voltage that the I \/ O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I \/ O pin could damage the board. \u003cbr\u003e\n \u003cbr\u003e\nSpecification: \u003cbr\u003e\nMicrocontroller: AT91SAM3X8E; \u003cbr\u003e\nOperating voltage: 3.3V; \u003cbr\u003e\nInput voltage(recommended): 7V - 12V; \u003cbr\u003e\nInput voltage(limits): 6V - 16V; \u003cbr\u003e\nDigital I \/ O pins: 54(of which 12 provide PWM output); \u003cbr\u003e\nAnalog input pins: 12; \u003cbr\u003e\nAnalog outputs pins: 2(DAC); \u003cbr\u003e\nTotal DC output current on all I \/ O lines: 130mA; \u003cbr\u003e\nDC current for 3.3V pin: 800mA; \u003cbr\u003e\nDC current for 5V pin: 800mA; \u003cbr\u003e\nFlash memory: 512KB all available for the user applications; \u003cbr\u003e\nSRAM: 96KB(two banks: 64KB and 32KB); \u003cbr\u003e\nClock speed: 84MHz; \u003cbr\u003e\n \u003cbr\u003e\nPackage included: \u003cbr\u003e\n1 x compatible DUE R3; \u003cbr\u003e\n1 x USB cable","brand":"GreenZech","offers":[{"title":"Default Title","offer_id":44964001611946,"sku":"GZMBN-2797-01-EC","price":52.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0280\/6179\/4375\/files\/SKU103944HH.jpg?v=1690448213","url":"https:\/\/greenzech.com\/products\/r3-32-bit-arm-module-development-board-with-usb-cable-geekcreit-for-arduino-products-that-work-with-official-arduino-boards","provider":"GreenZech","version":"1.0","type":"link"}
