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.
SPI Interface
The module uses SPI and can connect to common controller boards such as Raspberry Pi, Jetson Nano, Arduino, and STM32.
