Product Overview
The Digital View EPM-050C interface board is designed for E Ink 13.3″ color reflective e-paper display panels such as ED133UJ1. 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.
Features
The display system design is broadly similar to working with LCD panels except that the driver board, EPM-050C has a USB interface for the transfer of bitmap images from a media source. Also, partial screen writes are possible enabling faster image updates and further reductions in power consumption.
