Signals marked with * are multiplexed with either a peripheral device or another connector. Ensure that the multiplexing is handled
properly on software and/or hardware level (else there would probably occur wrong levels, loss of data, etc).
The LCD connector is suitable for a number of Olimex displays and touchscreen panels with
different native resolution – the smallest available is the
4.3''
one called
A13-LCD43TS
with native
screen resolution of
480×272
, through the
7''
one named
A13-LCD7
with
800×480
, to the
1024×600 10.1''
A13-LCD10.
IMPORTANT:
To use Android with display or resolution different than HDMI and 1024×600 (default settings) you
need to upload new Android image to the board. These images are available here:

(using an operating system – NAND flash).
