Small and cheap E-Ink Displays

[Coventry]

Does anyone know of any small and cheap e-ink displays?

I’m working on a potentially battery powered project, but the display always becomes an issue due to the amount of mah it pulls. It needs to always display a value, but that value can remain unchanged for long periods, so the circuit really only needs to wake up every 10-20 minutes, pull some data from the sensors, update a display, and then sleep again.

For a low-power, battery-powered project, an e-ink display is a great choice since it only consumes power when updating the display. A small, affordable option is the Geniatech E-Paper Display, which is energy-efficient and ideal for projects needing periodic updates. It can hold an image without power for long durations, making it perfect for your use case where updates are needed every 10-20 minutes. This helps conserve battery life, allowing for longer operational time between charges.
