- 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:
- Turing Smart Screen 3.5"
- Turing Smart Screen 5"
- XuanFang 3.5" (rev. B & flagship)
- "UsbPCMonitor" 3.5" & 5"
- Kipye Qiye Smart Display 3.5"
This is the official smart screen made by Turing.
It is sometimes incorrectly labeled as "revision A" by resellers.
There is 2 USB-C ports.
The mention "Turing Smart Screen" is visible in English and Chinese when there is no backplate.
It is originally provided with UsbMonitor.exe software for Windows.
Serial ID: USB35INCHIPS / USB35INCHIPSV2
Note: for this version you may need to disable self.lcd.Reset() in def initialize_display(self): from library/display.py
This 5" model made by Turing is also supported by this project (themes are different for 3.5" and 5" models)

There may also be a MX-1.25 connector for motherboard USB connection.
Model is available in black or white casing.
