## Common characteristics
- MCU – WCH [CH552T](http://www.wch-ic.com/products/CH552.html) 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](https://github.com/mathoudebine/turing-smart-screen-python/wiki/Vendor-apps) 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:
* [**Turing Smart Screen 3.5"**](#turing-smart-screen-35)
* [**Turing Smart Screen 5"**](#turing-smart-screen-5)
* [**Turing Smart Screen 8.8"**](#turing-smart-screen-88)
* [**Turing Smart Screen 2.1" (round)**](#turing-smart-screen-21-round)
* [**XuanFang 3.5" (rev. B & flagship)**](#xuanfang-35-rev-b--flagship)
* [**_"UsbPCMonitor"_ 3.5" & 5"**](#usbpcmonitor-35--5)
