Arduino Due Development Board

the Arduino Due board runs at 3.3V (which is different to most other Arduino boards). Applying voltages higher than 3.3V to any I/O pin may cause damage. Arduino Due Development Boards. The Arduino Due is a development board based on the Atmel SAM3X8E microcontroller. The SAM3X8E is a 32-bit, ARM Cortex M3.. How to get started:. The Arduino Due already has everything on-board to support the MCU. Simply connect it to a PC via microUSB cable or power it via an AC-to-DC adapter or battery. (Please note these are not included). What else is on-board?. Atmel SAM3X8E Microcontroller 54 x digital I/O pins (12 can be used as PWM outputs) 12 x Analogue inputs 4x UARTS 84 MHz quartz crystal 1 x USB OTG 2 x DAC 2 x TWI 1 x power jack 1 x SPI header 1 x JTAG header 1 x reset button 1 x erase button. Operating Voltage : 3.3V FLASH Memory : 512 KB SRAM : 96 KB Clock Speed : 84 MHz Dimensions : 101.52 x 53.3 mm. Does it work with the Arduino Shields?. Yes, the Due board works with all available Arduino Shields that run at 3.3V and are compliant with the 1.0 Arduino pinout: - TWI : SDA and SCL pins that are near to the AREF pin. - IOREF : allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V. - An unconnected pin, reserved for future use.
