1.2 Target market and purpose of the board
The boards from the OLinuXino family are easy to setup and powerful. It is possible to use them in
almost any application as a host board. They are suitable for embedded programming enthusiasts,
Linux and Android gadget fans (they can just use the board as a media center or fully functional
Linux-PC, for instance) and also professionals (since its low cost makes it very good solution for
application-orientated embedded systems). The main usage of the board is software embedded
development without the urge of understanding perfectly the hardware.

The strong points of the boards are the processor speed, the small form factor and the low price-to-
productivity ratio.

1.3 Board variants
There are two major board variants named: A20-OLinuXino-MICRO-4GB and A20-OLinuXino-
MICRO. The 4GB version has a built-in NAND memory suitable for the storage of an operating
system without the need of a SD card. The 4GB version comes with already programmed Android
4.2.2 image.

The other Olimex boards with close characteristics are the ones with A13 and A10/A10s
microcontrollers. The A13 boards feature a generation older processor but since they have been
longer on the market they have better Linux and Android support. The A10/A10s boards feature
single (than A20) processor core but they are more energy efficient making them better choices for
handheld devices and devices requiring power efficiency.

Additional Android and Linux support and features are added overtime. The Linux support is a
work in progress and you should not expect full Linux support after the initial volume of such
boards have become available on the market. If you are in a hurry consider the older OLinuXino
designs (which have almost everything supported, have examples available and so on).
