Arduino Due R3 Arm 32-bit Development Board (Compatible)

AED 228.90



The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. 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, an 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. The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with an AC-to-DC adapter or battery to get started. The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically.

It is possible to erase the Flash memory of the SAM3X with the onboard erase button. This will remove the currently loaded sketch from the MCU. To erase, press and hold the Erase button for a few seconds while the board is powered.

The main differences are:
• 32 bits at a clock can process 32 bits of data.
• CPU clock frequency of 84 MHz
• 96 SRAM KBytes
• 512 Flash KBytes
• A DMA controller, can reduce the pressure on the CPU to do a lot of computing

• Microcontroller: AT91SAM3X8E
• Operating voltage: 3.3 V
• Input voltage (recommended): 7 - 12 V
• Input voltage (limits): 6 - 16 V
• 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 3.3 V pin: 800 mA
• DC current for 5 V pin: 800 mA
• Flash memory: 512 KB all available for the user applications
• SRAM: 96 KB (two banks: 64 KB and 32 KB)
• Clock speed: 84 MHz
