4-inch (640 x 400 pixel) 7 colour electronic paper display for Raspberry Pi

New ePaper screens just keep getting better! We can't resist them with their delicious crispness, impressive low power credentials and enticing viewing angles (even in bright sunlight). This 4" eInk display is positively bulging with pixel density and bright strong colours, and we've fitted it with all the necessary apparatus to interface with a Raspberry Pi cleanly, humanely and without fuss.
