Arduino Mini Uno
The World's Smallest Arduino Uno Board
miniUNO is a microcontroller board based on the
ATmega328P-MU ( datasheet ). It has 14 digital input/output
pins (of which 6 can be used as PWM outputs), 6 analog
inputs, a 16 MHz ceramic resonator, a micro USB connection,
a 3.5mm power jack, an ICSP header and a reset button. It
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.
It is completely compatible with the Arduino Integrated Development Environment (IDE), also has a
preloaded bootloader of the original Arduino Uno, so it will act as a normal Arduino Uno when plugging it to
PC using the micro USB cable.
miniUNO has the same specification of the Arduino Uno, same hardware, also the same look-like when it
comes to its shape and the positioning of its components; but yet quarter the size .
