3.7″ e-Paper e-Ink Display for Raspberry Pi Pico (480×280)
Looking for an e-Paper display for your Raspberry Pi Pico? Look no further! This 3.7″ 480×280 black/white e-Paper display from Waveshare is perfect for adding a low-power display to your Pico.
e-Paper displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which lose their image when power is removed, e-Paper displays are able to hold text and images indefinitely, even without power! ePaper screens are therefore ultra low power, designed to have a wide viewing angle and additionally have limited reflection under sunlight. The applications are limitless!
Your Raspberry Pi Pico slots into the female connectors on the back of the display, then you simply power the entire setup via the Pico’s micro-USB connector – no need for additional power supplies. The display includes corner standoff mounting points and comes complete with 4 metal standoffs for fitting to your own panel or enclosure.
This display communicates via the SPI interface and supports partial refresh.
Note: Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
