Common characteristics

  • MCU – WCH CH552T 8-bit E8051 core MCU for 3.5" USB devices

The USB-C smart screens are detected as serial ports once connected.
They cannot be seen by the operating system as monitors, but pictures & dynamic content can be displayed on them.
A Windows-only software is provided by the vendor to manage the display. The vendor app allows creating themes to display your computer sensors on the screen, but does not offer a simple way to display custom pictures or text.

Here are the supported smart screen models for this project:
