Looking for an eInk / ePaper display for your Raspberry Pi Pico? Look no further! This great little 2.9" black/white eInk/ePaper display from Waveshare is perfect for adding a low-power display to your Pico project.
This display module has been designed specifically for the Raspberry Pi Pico - just push your Pico into the female headers and you're ready to go (Pico with male headers required).
ePaper / eInk displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which lose their image when power is removed, eInk screens 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!
The E-Ink display modules from Waveshare come complete with an embedded controller PCB, communicating via SPI interface and supporting partial refresh.
A Raspberry Pi Pico is not included - click here if you'd like to buy one. Your Pico will need to have male headers soldered to it with the pins pointing downwards (or grab one of our Pre-soldered Picos).

2.9" Black/White E-Ink E-Paper Display Module for Raspberry Pi Pico (296×128)
Arrived quickly and basically works, but readers should be aware that "partial updates" only seem to work after a previous "full update" IN THE SAME SESSION.
So for example, you cannot "start the device up and only do partial updates then sleep" - you must have at least one full update in the power-on cycle. Without this full update, the display memory appears corrupted by the sleep cycle, even if your "partial update" is the full screen.
In my tests a full update only takes 2.2seconds however.

2.9" Black/White E-Ink E-Paper Display Module for Raspberry Pi Pico (296×128)
!* No circuit python support *!
The 2.9" Black/White E-Ink E-Paper Display Module for Raspberry Pi Pico is a crisp display, which is fast to update (for E-paper).
The mounting board is convenient to mount a pico using male headers - but provides enough room for you to break out unused GPI pins.
The waveshare provided code examples work easily with micro-python.
The drawback of this unit is a (current) lack of support for circuit python. I'm sure this problem will be solved in time, but as of May 2021 this screen cannot be used with circuit python libraries (such as HID support, gfx etc...).
