The typical A13-SOM user would not need to edit the files, however.
2.7 Connecting and calibrating a display
A13-SOM itself has no direct way of connecting an Olimex display (with or without touchscreen
component). Using a display without A13-SOM-WIFI is possible via cables but hard to accomplish
and impractical. It is recommended to try to use a display only if you also have A13-SOM-WIFI at
your disposal.
Unlike other OLIMEX Allwinner boards, the A13-SOM lacks a row of pins that allows the user to
connect a display out-of-the-box. The board's LCD_TR connector is female and has a smaller 0.05''
step. This means that if you use a display made by OLIMEX, you would need additional 2×20
MALE-MALE 0.05'' header to convert the female connector to male. The 0.05'' headers are
somehow hard to find so we sell them here:
0.05'' step connectors . There is also something very
important to notice – since a stand-alone A13-SOM gets powered by 3.3V – this means that you
will not be able to power the display via the board (the Olimex-made displays require 5V of
voltage). You would need to power the display externally.
Newer displays made by Olimex have both 0.1'' and 0.05'' step connectors. So if you are going to
need only the display and a cable (sold separately).

The displays whose names contain “TS” - include a resistive touch screen component.
The cable used for connection depends on the specific board you are using and more specifically it
depends on the pitch of the LCD connector of the board. We have two cables – both 40-pins ones
but one for the bigger pitch (0.1'') and the other for the smaller one (0.05''). Each of the displays
listed in the table above has two connectors suitable for both cables:
CABLE-IDC40-6cm – 6cm long cable suitable for 0.1'' step connectors – Product page
CABLE-40-40-10CM – 10cm long cable suitable for 0.05'' step connectors – Product page
