  • AT91SAM3X8E ARM 32-bit Microcontroller @ 84MHz
  • Operating Voltage: 3.3V
  • 54 digital I/O pins, 12 analog inputs, 2 DAC (analog output)
  • Flash Memory: 512 KB all available for the user applications
  • SRAM: 96 KB (two banks: 64KB and 32KB)

The Arduino Due is the newcomer microcontroller board in the Arduino boards family. It's the first board based on a 32 bit ARM core processor, the Atmel SAM3X8E ARM Cortex-M3 MCU, that improve all the standard Arduino functionalities and add more new features. It offer 54 digital input/output pins (of which 12 can be used as PWM outputs, with selectable resolution), 12 analog inputs with 12 bit of resolution, 4 UARTs (hardware serial ports), and two DAC outputs (digital to analog converter), 84 MHz crystal oscillator, two USB connections, a power jack, an ICSP header, a JTAG header, and a reset button. The maximum voltage that the I/O pins can provide or tolerate is 3.3V. Providing higher voltages, like 5V to an input pin could damage the board. The Due has two usb connectors, the one with the micro-usb AB connector is the native one capable to act as an USB host, that means you can connect compatible external usb peripherals to the board, such as mouse, keyboards, smartphones. While the other USB port with the type B connector is intended for debugging purposes. Technical Specifications Microcontroller AT91SAM3X8E Operating Voltage 3.3V Input Voltage (recommended) 7-12V Input Voltage (limits) 6-20V Digital I/O Pins 54 (of which 12 provide PWM output) Analog Input Pins 12 Analog Outputs Pins 2 (DAC) Total DC Output Current on all I/O lines 130 mA DC Current for 3.3V Pin 800 mA DC Current for 5V Pin 800 mA SRAM 96 KB (64 + 32 KB) Clock Speed 84 MHz

Fritzing: an Electronic Design Automation software

Image
Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product. We are creating this software in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing. The complementing website helps users to share and discuss drafts and experiences as well as to reduce manufacturing costs. Fritzing is essentially an Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard, so that it is easy to transfer your hardware sketch to the software. From there it is possible to create PCB layouts for turning it into a robust PCB yourself or by help of a manufacturer. Why Fritzing is needed Physical prototyping tools have come a long way and already allow non-engineers to quickly turn their ideas in
