What is e-paper and why is it so low power?

E-paper (e-ink) displays hold an image with no power and only draw current while updating, which is why they can run for months on a battery. They are reflective, so they stay readable in sunlight, but they refresh slowly and usually offer limited colors.

Can I drive a display like this from a Raspberry Pi or ESP32?

Hobby displays connect over HDMI, USB-C, SPI, or I2C, and the right host depends on that interface. Check the interface and the available driver or library before buying; BooLabz publishes those details on each product page once they are confirmed.
