A000062

The A000062 is an Arduino Due development board based on the AT91SAM3X8E ARM Cortex-M3 microcontroller. It is the first Arduino board based on a 32bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analogue inputs, 4 UARTs (hardware serial ports), a 84MHz clock, an USB OTG capable connection, two DAC (digital to analogue), two TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. The board contains everything needed to support the microcontroller, simply connect it to a computer with a micro USB cable or power it with a AC to DC adapter or battery to get started. The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout. The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically.

• Input voltage (recommended) range from 7V to 12V
• 3.3V operating voltage
• 96KB of SRAM
• 130mA of total DC output current per I/O lines
• Input voltage (limit) range from 6V to 20V
• The Arduino Due can be programmed with the Arduino software
• The maximum length and width of the Arduino Due PCB are 4inch and 2.1inch respectively
• 1.0 pinout
• A DMA controller, that can relieve the CPU from doing memory intensive tasks
• 512KB of flash memory for code

警告

The Arduino Due 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.
