WAVESHARE 5 inch Touch Screen Expansion for Raspberry Pi CM4, PoE Header, Gigabit Ethernet, 4K Output

Product information
I am a Raspberry Pi CM4 kit with a 5-inch touch screen all-in-one machine. Gigabit Ethernet port with PoE pin supports 4K output, built-in four-way USB 2.0, 5-inch touch screen, etc. The all-in-one kit is convenient for users.
Notes:
1. Do not connect or disconnect any device except USB and HDMI while the base board is working.
2. If you need to replace the fan, confirm the fan voltage and then turn on.
3. The USB SLAVE interface is used to burn the image and cannot be used as an OTG interface.
4. In normal use, CM4 should be powered by at least 5V 2.5A. Otherwise, it may cause problems such as automatic shutdown, frequency reduction and so on.
5. Built-in default 4-way USB 2.0 interface.
6. Support POE pins, additional POE HAT is required if POE function is required.
7. This screen needs to add a driver to work.
