What is it?

Just another Arduino Compatible Board but this time its a DUE-CORE.

DUE-CORE is a compact version of Arduino DUE, It integrates all peripherals required for MCU & all GPIO are connected to the 2.54mm connectors for users.

What makes it special?

As a standard MCU core board, apart from main the features with DUE also has the following features:

• Compact size: All components are put on a 54 x 58mm 4-Layers PCB.

• All I/O are connected to 116pin 2.54 standard connector.

• User can integrate the Due Core to any application even the size is very compact.

• Easy to use: All IO are connected to 116 pin (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 setup the development environment: uploading sketch through standard 6pin UART interface, standard Micro usb connector, full use of existing resources.

• User-friendly design: Rich LED status indication, two onboard buttons, one is for MCU reset , and other one is for Flash Erase.

• Unique jumper erase protection against the flash erased by mistake operation.

• Rich resource : All IO are connected out for the user.

• Onboard I2C EEPROM designed to compensate for the shortcomings of SAM3X8E no built-in EEPROM.

Warning:

Unlike other Arduino boards, the Arduino DUE-Core 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.
