Arduino DUE R3 Compatible SAM3X8E 32-bit ARM Cortex-M3 Breakout Board
As you may already know, the Arduino Due was Arduino’s first ARM-based Arduino development board. This board is based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the familiar Arduino IDE. It increases the computing power available to Arduino users keeping the language as compatible as possible so that many programs will be migrated in a matter of minutes!
The DUE was so powerful, many people were embeddeding it into complex or commercial applications, so to make this process easier - or for those who want to use the powerful SAM3X8E MCU on their own board - PMD Way now offers the awesome DUE CORE.
The DUE-CORE is a compact version of the Arduino Due which integrates all peripherals required for the MCU, and all GPIO are wired to the 2.54mm connectors for users.
As a standard MCU core board, apart from main features with DUE also has the following features:
Compact size: All components are put on a 54 x 58mm 4-Layers PCB. All IO are connected to 116pin 2.54 standard connector. User can apply the PCBA to any application even the size is very compact.
Easy to use: All IO are connected to 116pin 2.54 standard connector. Only a 5V power to the board to make it work.
Stable design: adopt high-cost 4-layer PCB layout , two 5V to 3.3V LDO onboard, one is for digital part and one is for analog part. Separate AVCC and AGND, to ensure the best analog performance.
Easy to set up the development environment: Fully development on Arduino IDE, uploading sketches through a standard Arduino/FTDI 6pin UART interface, standard micro USB connector, offering full use of existing resources.
A user-friendly design: Rich LED status indication, two onboard buttons, one is for MCU reset, and other one is for Flase Erase. Unique jumper erase protection against the flash erased by mistake operation.
Rich resources - all the I/O are connected out for the user, even if not defined in the Arduino specification. Onboard I2C EEPROM designed to compensate for the shortcomings of SAM3X8E (which doesn't have a built-in EEPROM).
