For Arduino Due R3 Board Arduino Due 32Bit ARM Microcontroller ARM Version Main Control Board
Description:
It is a microcontroller board based on the Atmel SAM3X8E CPU, which is the first one based on 32-bit ARM core arduino.
It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a USB-OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
ARM Core Strengths:
The use of 32 bit ARM core Due compared to the previous use of the other Iduino core 8 AVR more powerful.
The main differences are:
- 32 bits at a clock can process 32 bits of data.
- CPU clock frequency of 84Mhz
- 96 SRAM KBytes
- 512 Flash KBytes
- A DMA controller can reduce the pressure on the CPU to do a lot of computing
Features:
- Microcontroller: AT91SAM3X8E
- Operating Voltage: 3.3V
- Input Voltage (recommended): 7-12V
- Input Voltage (limit): 6-20V
- Digital I/O Pins: 54 (of which 12 provide PWM output)
- Analog Input Pins: 12
- Analog Output 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
- Flash Memory: 512KB all available for the user applications
- SRAM: 96 KB (two banks: 64KB and 32KB)
- Clock Speed: 84 MHz
Package Included:
- 1 x Arduino Due R3 Board
Note: This is not the same as other Arduino boards, 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.
