Why E-Paper

E-paper reflects ambient light like printed paper, stays readable under lamplight or natural light, and keeps the last displayed content after power is removed.

Raspberry Pi 40PIN GPIO Header

The standard 40PIN GPIO header supports Raspberry Pi series boards. Raspberry Pi shown in reference images is not included.

Display and Touch Interfaces

The display is controlled over SPI, while the capacitive touch panel uses I2C.
