Note: The above image shows the original model of the EPM-050, the new model to be released in Q4, 2021 is the same length and width but is thinner.
Interface driver board for E Ink 13.3" monochrome panels.
• Inputs: Micro USB
• Panel support: E Ink 13.3"
• Power: 5VDC or 12VDC (select)
• Part number: 4160245xx-3
The Digital View EPM-050 interface board is designed for E Ink 13.3" monochrome reflective e-paper display panels. This low power interface accepts an image transferred over USB from a source media player such as a Raspberry Pi or Android PC. E Ink based displays are ideal for public signboards, transport information displays and similar. The significant benefits include the high visibility in bright environments as well as the ability to operate from solar power due to the very low power consumption.
The display system design is broadly similar to working with LCD panels except that the driver board, EPM-050, has a USB interface for the transfer of bitmap images, not video. We will be preparing a guide to working with E Ink panels, in the meantime contact us and we will be happy to explain.
Custom driver board layout with additional functions or integration is available as an engineering service. In addition Digital View can assist with display bonding and other integration requirements for the E Ink panel. See also, the 32" and 42" outdoor display which is design as the basis for outdoor project development: Outdoor display.
|Panel Connectivity||Panel connection: E Ink 13.3" (ED133UT3 models)|
|Resolution||For 13.3": 1600 x 1200|
|Functions||Image rotation: 180 degrees
Image mirror (horizontal flip)
Built-in temperature sensor
16 level grey scale mode
|Input||Micro USB (for image transfer & 5VDC power)|
|Power||Power input 5VDC default, 12VDC selectable (jumper)
Power output (option): 5V DC for (for 12V input only) Raspberry Pi
Standby power consumption (as meaasured):
13.3" Panel + EPM-050 + = 0.5W
Raspberry Pi3 (Model B+) = 0.32A x 5VDC = 1.6W
During image write to panel (as measured):
13.3" Panel + EPM-050 + x 12VDC = 1.5W
Raspberry Pi3 (Model B+) = 0.61A x 5VDC = 3.05W
|Image file||Supports bitmap (bmp) file format|
0°C to +60°C
(note: extended temperature tests are pending and will be advised later)
|Reliability||MTBF in excess of 200,000 hours @ 25oC (calculated using Telcordia SR-332 procedure)
Warranty 3 years

As a public signage display, the normal system will have a media player, for example a PC, Android PC or Raspberry Pi. The Raspberry Pi model 3B or 4 appears to be sufficiently powerful for most purposes so we have used it for further development. The following appnotes show example methods for updating the image using a Raspberry Pi Model 3 B+ together with the EPM-050 driver board and a compatible E Ink panel (NOTE: The applications referenced in these appnotes is available for free to EPM-050 customers):
- From PC to USB (PDF)
- Via Google Drive (PDF)
- Via network (PDF)
In addition we have been working with live data feeds, for example retrieving weather data from public sources, formatting it then writing it to the display.
Another function is partial screen update, this capability enables just updating the part of the display where the content has changed. This reduces the power used and can be useful for very low power installations.
LOW POWER & SOLAR
As the E Ink panel is reflective and bistable it is uniquely suited to outdoor installations powered via a solar panel with rechargeable battery. Power reduction methods might include almost completely powering off the system and only powering up to perform intermittent content checks and updates. To facilitate this we have a pic processor powered timer relay
Shown below are complete 32" and 42" IP65 rated displays as well as bonded 13.3" panels for display developers.
13.3" optically bonded panels for outdoor ePaper displays. Design your enclosure around these panels:
- Optically bonded cover glass, UV layer together with a backing plate
- Matching driver is Digital View EPM-050, limited engineering samples are available
- Option: Raspberry Pi 3B+ with Wi-Fi with customizable application to accept JPG or BMP images.
- Option: Cellular network support.
- Option: Low power timer for system sleep/wake power saving.
- Option: Solar and/or wind power solutions.
