                  This 800x400 E-paper display module has advanced colour ePaper technology which makes it a more comfortable read than a conventional display, due to a stable image, not having to be refreshed constantly, a wider viewing angle, and the fact that it reflects ambient light rather than emitting its own light. Thanks to its low-power feature it can retain text and images even when the power is off.
With an SPI control interface to use development boards like Raspberry Pi, Arduino, STM32 and others, a lovely 7-colour display, and a 40-pin GPIO header for an easy connection to your Raspberry Pi. This is a great display for lots of different projects, including price tags, shelf labels, industrial instruments, and many more!
Note: This does NOT come with the Raspberry Pi board
