About The Product I am a Raspberry Pi CM4 kit with a 5 inch touch screen all-in-one machine. The PoE pin Gigabit Ethernet port supports 4K output, onboard four-way USB2.0, 5-inch touch screen, etc. The all-in-one kit is convenient for users. Notes: 1. Do not plug and unplug any device except USB and HDMI while the baseboard is working. 2. If the fan needs to be replaced, please confirm the fan voltage and then power on. 3. The USB SLAVE interface is used to burn the image and cannot be used as an OTG interface. 4. In normal use, it is necessary to provide at least 5V 2.5A power supply for CM4. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on. 5. Onboard 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. Specifications 1.
