Xteink X4 by Xteink
The Xteink X4 is an ESP32-C3 based board with a built-in 4.26” e-paper display (800×480 resolution) using an SSD1677 controller driving a GDEQ0426T82 e-ink panel. The ESP32-C3 provides Wi-Fi and Bluetooth Low Energy connectivity.
The board features 16MB of flash storage and uses SPI to communicate with the e-paper display. It includes a boot button for entering safe mode. The display is initialized automatically on boot with CircuitPython’s displayio/epaperdisplay support.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
