Product Specification
EPD Driver Board
Page 6 of 12
The supported values for the gate supply voltage of EPDs are shown in the
table below.
To display a graphic information on the display from a memory card, you must
use a card with a size of up to 32 GB. The card must have a 32-bit FAT32 file
system. At the same time, the memory card should contain not only graphic
information, but also a configuration file, without which the driver does not
boot. This file must contain display information and additional driver settings.
Creation of the configuration file
The file of configuration allows to set the board’s output parameters according
to the driving EPD display. The config.ini file is placed in the main folder of SD
card. If there is no any config.ini file or any mistake takes place the board
shows an error by LED Error lightning.
There are several main settings, which can be critical for the panel usage. The
example below describes the configuration for ED133UT2. The comments (#) explain
the command lines.
