Free Shipping Within The United States!
MicroSD card and battery (CR1220) are not included!
The jCOM.DUE.CORE-C board combines two of our products into one:
- Dual CAN Bus Interface for Arduino Due
- Due Core - Arduino Compatible SAM3X8E 32bit ARM Cortex M3 Module
In addition, we have added two proven Adafruit components:
Further onboard components are:
- A 4-pos. DIP switch, readable per digital input
- 4 push-buttons, also readable per digital input
- 8 LEDs, controllable per digital output
- 2 x UART port, compatible with:
The CAN Bus section incorporates dual CAN transceivers required by the two integrated CAN ports on the Arduino Due, i.e. they convert the CAN TTL signal into a differential voltage as required by the CAN Bus Standard (ISO 11898).
The jCOM.DUE.CORE-C board is powered either by the USB port connection (either the programming or native USB) or through an external power supply supporting an input voltage of 7 to 36 VDC.
The Due Core is a microcontroller board based on Arduino Due, featuring the Atmel SAM3X8E ARM Cortex-M3 CPU. It integrates all peripherals required for the MCU, and all GPIO are connected to 2.54mm connectors. As a standard MCU core, the board has the following features:
- Compact size: All components are put on a 54 x 58mm 4-Layers PCB. All IOs are connected to a 116-pin 2.54 standard connector.
- Easy to use: All IOs are connected to 116pin 2.54 standard connector. It requires only a 5 VDC power supply to make it work.
- Stable design: High-quality 4-layer PCB layout, two 5V to 3.3V LDO onboard, one for digital and one for analog processing. Separate AVCC and AGND, to ensure optimum analog performance.
- Easy to set up the development environment: Uploading sketches through standard 6-pin 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 one is for Flash Erase. Unique jumper erase protection against the flash erased by mistake.
- Rich resources: All IOs are available for the user. The onboard I2C EEPROM is designed to compensate for the shortcomings of the standard SAM3X8E, which has no built-in EEPROM.

Programming Arduino - Getting Started With Sketches
by Simon Monk
Clear, easy-to-follow examples show you how to program Arduino with ease! "Programming Arduino: Getting Started with Sketches" helps you understand the software side of Arduino and explains how to write well-crafted Sketches (the name given to Arduino programs) using the C language of Arduino. This practical guide offers an unintimidating, concise approach for non-programmers that will get you up and running right away.
Programming Arduino: Getting Started with Sketches explains basic concepts and syntax of C with simple language and clear examples designed for absolute beginners - no prior knowledge of programming is required. It leads you from basic through to advanced C programming concepts and features dozens of specific examples that illustrate concepts and can be used as-is or modified to suit your purposes.
- All code from the book is available for download.
- Helps you develop working Sketches quickly.
