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), a 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.

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.

Q: hello TechShop . I bought a due from you . but now i see you sell product doesn't match your description .... totally different from your showen image in this pagee.... why ???????????????????????????? Questioned by CopperMasud, 17-Mar-2015

What difference did you find? Answered by A.R, 18-Mar-2015 09:15 AM

Q: in your shoWn image there's external oscillator and filter caps for that avaiLable....................... but the one you gave me - that place is empty ..... you should've describe this in your page >>>>>>> Questioned by CopperMasud, 18-Mar-2015

heyy TechShopp >> don't wanna talk about it ?????? Answered by CopperMasud, 20-Mar-2015 10:54 AM

Let us check one from our store first. Answered by A.R, 20-Mar-2015 13:02 PM

let me know please ... how that will run me @ 84 MHz without external oscillator ?? it running @it's internal source maybe ..... you should've described . Answered by CopperMasud, 21-Mar-2015 08:33 AM

Arduino Due made by AT91SAM3X8E chip. Its internal oscillator up to 84MHz. Answered by Production, 22-Mar-2015 12:07 PM

so , without an external oscillator - is it working @ 84 MHZ ?????? Answered by CopperMasud, 23-Mar-2015 22:18 PM

hello Answered by CopperMasud, 05-Apr-2015 22:35 PM

Yes.As per datasheet. Answered by A.R, 07-Apr-2015 10:18 AM

Q: I have a fully functional Arduino DUE Made in China...I find it difficult to use it for my purpose for 3.3v Sensor compatibility and lack of proper libraries...can i Exchange My Arduino DUE with an Arduino Mega? Questioned by tausif, 21-Jan-2017

Sorry. Not possible. Answered by A.R, 22-Jan-2017 09:43 AM

Q: Is it compatible with the same libraries of UNO? Questioned by Craftsman, 05-Dec-2018

Yes. Answered by A.R, 06-Dec-2018 09:55 AM
