The XTEINK X4 is a small 4.26" four-grayscale e-ink reader on an ESP32-C3 with 16 MB of flash. Reflashed with FrameOS it becomes a pocket-sized frame - and 800×480 on a 4.26" panel is a lot of pixels per inch, so small text stays legible.
The C3 has no PSRAM, so FrameOS runs this board as a thin client: your backend renders the scene and the device streams the packed panel bytes. The backend has to be reachable when the frame renders.
The X4's card slot shares its SPI bus with the e-paper controller, so SD-card assets are turned off on this board.
Setup

- Choose ESP32-C3, select the XTEINK X4 preset, and enter your WiFi details.
- Build the firmware and flash it over USB from the browser.
- Install scenes as usual.
