4.2-inch three-color + 2.13-inch black and white combined e-paper display enclosure + night light

1. E-paper display enclosures are all the same, just a few types. I had a sudden idea: why not change the shape, for example, to a heart shape? To make full use of the space, the screen layout was optimized, and a heart-shaped button (responsible for the night light switch added to the back) was specially included.

2. The model has been successfully tested;

3. The internal 4.2-inch screen can use the open-source firmware from tsl for NRF52/NRF51 main controllers (it is recommended to purchase his paid firmware, which supports image carousel), or other 4.2-inch e-paper calendar projects;

4. The second heart shape on the right is a physical button, internally adapted for a tactile switch measuring 6mm long, 6mm high, and 4mm wide. You can also adapt the model yourself.
