Overview
This is a 7-inch touch screen all-in-one kit designed for Raspberry Pi CM4. CM4-DISP-BASE-7A-BOX ,7~36V DC power supply, Onboard four-way USB2.0, 7-inch touch screen, etc., the all-in-one kit is convenient for use.
Precautions for use
1: Do not plug and unplug any device except USB and HDMI when powered on.
2: If the fan needs to be replaced, please confirm the fan voltage and then power it 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 a 12V 1A 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: POE function is not supported.
8: The screen requires a driver for working.
