The is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.
DUE-CORE is a compact version of DUE , It integrates all peripherals required for MCU , and all GPIO are connected 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: 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 Flase 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.
Onboard 512K EEPROM (AT24C512C) connection to TWD1 (SDA = PB12 , SCL = PB13).
