ARDUINO DUE BOARD

INTODUCTION OF ARDUINO DUE BOARD

Arduino Due Board provides clock pulses of 3.579
Mhz frequency .
Arduino Due Board are very common and inexpensive
they are used in many other applications, for
example DTMF generators.
It uses the mechanical resonance of a vibrating
crystal of piezoelectric material to create an
electrical signal with a very precise frequency.
This frequency is commonly used to keep track of
time to provide a stable clock signal for digital
integrated circuits and to stabilize frequencies
for radio transmitters and receivers.
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 Due is compatible with all Arduino shields
that work at 3.3V and are compliant with the 1.0
Arduino pinout.
The Arduino Due can be powered via the USB
connector or with an external power supply.
