1.54-Inch E-Ink e-Paper Display Module (Black/White, SPI)

A paper-like display for ultra-low-power projects

This 1.54 inch e-Paper module has a 200 x 200 resolution, an embedded controller and an SPI interface with partial refresh support. Like a printed page, it needs no backlight and it keeps its last picture without power for a long time, which makes it ideal for name badges, price tags, sensor stations and any battery-powered device that updates rarely.

It works with 3.3 V and 5 V microcontrollers, including Raspberry Pi and Arduino boards.

Specifications

The working voltage is 3.3 V and communication is 3-wire or 4-wire SPI. The module measures 48 x 33 x 1.05 mm with a display area of 27.6 x 27.6 mm. It shows black and white with two grey levels. Refresh power is 26.4 mW, standby power is under 0.017 mW and the viewing angle is more than 170 degrees. The package includes the module and a cable.

E-paper refreshes slowly compared with LCDs and OLEDs, so it suits static content. Avoid refreshing too often, follow the maker's recommended refresh interval and do a full refresh from time to time to clear ghosting.

Who it suits

Makers of low-power signs, e-readers, weather displays and IoT nodes that spend most of their time asleep.

Refresh tips

Send the image data over SPI, then trigger a full or partial refresh with the maker's command. Partial refresh is faster and leaves less flicker, but it can leave faint ghosts, so run a full refresh every so often. Put the display to sleep after each update to save power, and never leave a static image powered for very long periods.
