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 LIME boards are a special kind of OLinuXino boards – they are as small as possible while
maintaining a remarkable stand-alone functionality. The strong points of these boards are the processor
speed, the small form factor and the low price-to-productivity ratio.
Customers have full access to the technical documentation of the board. The software is released under
General Purpose License and the board is considered open-hardware – all schematics and board design

1.3 Board variants
The board has four major board variants. The difference in the suffix is based on the type and volume of
extra flash memory installed on the board. The base version of the board, that comes with NO extra flash
memory is named
A20-OLinuXino-LIME2
. These three variants with extra flash memory are named:
A20-OLinuXino-LIME2-e4GB
,
A20-OLinuXino-n4GB
, and
A20-OLinuXino-LIME2-n8GB
. The
name consists of the type of the memory and the size of the memory – suffix “
e4GB
” stands for eMMC
type of flash with 4GB of size; “
n4GB
” stands for NAND type of flash with 4GB of size.
The
e4GB
version comes with 4GB eMMC flash memory that expands the on-board storage available
and also allows booting the operating system without the need of a SD card. The eMMC memory comes
blank (you would have to upload desired operating system to the eMMC memory).
Exactly the same is the case with the
n4GB
and
n8GB
variants. The
n4GB
and
n8GB
versions come
with either 4GB or 8GB extra NAND flash memories expands the on-board storage available and also
allows booting the operating system without the need of a SD card. Note that these memories also come
blank (you would have to upload desired operating system to the NAND memory).
Currently, there is higher demand for boards with eMMC since seem to require less power, have longer
life, corrupt harder. Additionally, the eMMC memories that we use have an industrial temperature range
version.
