The Pimoroni Inky Frame 4.0" is a 640×400 seven-colour ACeP e-ink display with a Raspberry Pi Pico W soldered to the back. FrameOS runs on it as a thin client: the backend renders and dithers the scene, and the Pico streams the packed panel bytes into the controller. A Pico W has 264 KB of RAM - far too little for an on-device renderer, but plenty to stream a picture.
The board's own battery latch is supported, so deep_sleep powers it right down between refreshes
and cold-boots on the next interval or a button press.
Setup

RPI-RP2drive. - Add a frame in the backend with Flash embedded device and the Pimoroni Inky Frame 4.0" preset.
- Provision it over the USB serial console - see the Pico guide.
