Arduino Due R3 Clone Model – 32-bit ARM Cortex-M3 Microcontroller Board

Description

he Arduino Due R3 Clone Model is an advanced, open-source microcontroller board built around the Atmel SAM3X8E ARM Cortex-M3 CPU. As the first Arduino board powered by a 32-bit ARM core, it redefines standard Arduino functionalities with enhanced performance and new features.

Key Features:

• Powerful 32-bit Processor:

  • ARM Cortex-M3 CPU operating at 84 MHz for robust, high-speed performance.

• Extensive I/O Capabilities:

  • 54 Digital I/O Pins: 12 of which support PWM output with selectable resolution.
  • 12 Analog Input Pins: Offering 12-bit resolution for precise sensor readings.
  • 2 Analog Outputs (DAC): For generating accurate analog signals.

• Dual USB Connectivity:

  • Micro-USB AB Connector: Functions as a USB host to connect external peripherals like keyboards, mice, or smartphones.
  • Type B USB Port: Dedicated to debugging and programming tasks.

• Memory & Bootloader:

  • 512 KB Flash Memory: (divided into two blocks of 256 KB) for code storage.
  • 96 KB SRAM: Organized in two banks (64 KB and 32 KB) for efficient data handling.
  • Preburned Bootloader: Stored in dedicated ROM for seamless programming.

• Power & Voltage Specifications:

  • Operating Voltage: 3.3V (Note: I/O pins are not tolerant of 5V inputs).
  • Recommended Input Voltage: 7-12V (with limits of 6-16V).
  • DC Output Current: 130 mA on all I/O lines; 800 mA available for both 3.3V and 5V pins.

• Additional Features:

  • Fully compatible with Arduino shields designed for 3.3V and adhering to the 1.0 Arduino pinout.
  • Onboard Erase Button: Quickly erase the SAM3X Flash memory to remove the current sketch and start fresh.
  • Compact and lightweight design (104 x 53 x 15 mm; 35 g), perfect for portable and space-constrained projects.

Quick Start:
Connect the board via USB for programming or power it with an AC-to-DC adapter or battery to dive straight into your next innovative project.
