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.
Four onboard keys are available for extended applications, making the HAT useful for compact interfaces and low-power display controls.
The standard 40PIN GPIO header supports Raspberry Pi series boards and Jetson Nano. Raspberry Pi shown in reference images is not included.
The HAT uses SPI and can also connect to controller boards such as Raspberry Pi, Jetson Nano, Arduino, and STM32.
