Arduino Micro
If you need to go smaller, the Arduino line also offers opportunities with much smaller
packages in a number of different form factors. One of the more popular units is the Ardu-
ino Micro. The Micro is a very small form factor; yet, it has a processor with the appropri-
ate boot parameters so that you can run the Arduino IDE, the USB connector, and the ex-
posed I/O pins, even though they are much fewer than those found in the Arduino Uno.
The following is an image of this unit:
Choosing the Arduino Micro
This unit comes with an ATmega328 processor, the same processor that comes with the
Arduino Uno, but runs at half the clock rate. It comes with the same 32 KB of memory as
the Uno but with much fewer I/O pins. For this unit, and the others that I will present here,
you'll need to use a mini-USB B cable, as shown in the following image:
