The EPD Driver Board is really special in the family of driver boards. The board has a sophisticated concept for industrial solutions.

The EPD driver has two connectors that match to the 13.3" ED133UT2 EPD display with 1600x1200 resolution and ES133TT3 with 2200x1650 pixels. A 50-pin connector is intended for expansion of the board. By means of a passive adapter-board a variety of EPDs can be connected to the EPD driver. Onboard voltage setting makes the board easy to configure for the wide range of e-paper displays.

The operation of the board can be realized in three different ways.

1. SD card

Functionality settings can be made in the "config.ini" file on the microSD card using simple commands. Display parameters (resolution, display size, VCom, grayscale) as well as slide show settings (image arrangement and delay between updates) can be configured. Image updates can be performed by pressing the buttons or by means of the built-in timer. The board can become a wireless and mobile solution in case the system is powered from an external battery.

2. SPI interface

Via classic SPI interface it is possible to manage the entire configuration of the display as well as display the bitmap on the screen.

3. USB interface

The board is recognized by host systems as a Virtual COM port and allows the settings and image transfer.

The ARM Cortex-M4 processor manages the processing of the large graphics files quickly. The extension of the circuit by external RAM and usage of DMA and new image update algorithms have made it possible to reduce the time of image construction significantly.

The dimensions of the EPD driver are 50mm × 100mm × 5mm.
