This product has reached end of life. Here's a list of ePaper modules we have available.

(EOL) 4.2" 3-Color ePaper Display

Part Number: CFAP400300C0-0420

4.2" Black, White, Yellow ePaper Display Module. 400x300 pixels. ePaper displays are perfect for applications that require super low power and infrequent updates such as electronic shelf labels, tags or static advertising.

The beauty of ePaper modules is that they only require power when being updated. Once the screen is displaying the graphic of your choice, you can disconnect the display entirely from its power source and it will continue to display indefinitely.

This ePaper is 3 colors; white, black and yellow. 4.2" Diagonal measurements and 400x300 pixel resolution.
