Due R3 Compatible Board with USB Cable

The 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.

The 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.

It 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.
