OSOYOO Due R3 32 Bit ARM Compatible Shield Module Board with USB Cable (Compatible with Arduino)

Specification:
Microcontroller: AT91SAM3X8EA
Operating voltage: 3.3V
Input voltage(recommended): 7V – 12V
Input voltage(limits): 6V – 20V
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: 130mA
DC current for 3.3V pin: 800mA
DC current for 5V pin: 800mA
Flash memory: 512KB all available for the user applications
SRAM: 96KB (two banks: 64KB and 32KB)
Clock speed: 84MHz

Warning:
Unlike 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.

Package included:
1 x Arduino compatible DUE R3
1 x USB cable
The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet)
It is the first Arduino board based on a 32-bit ARM core microcontroller
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 bootloader is preburned in factory from Atmel and is stored in a dedicated ROM memory. The available SRAM is 96KB in two contiguous bank of 64KB and 32KB. All the available memory (Flash, RAM and ROM) can be accessed directly as a flat addressing space
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
