Overview

This is a 7inch touch screen all-in-one kit designed for Raspberry Pi CM4. CM4-DISP-BASE-7A-BOX supports POE power supply and 7~36V DC power supply, Onboard four-way USB2.0, 7-inch touch screen, etc., the all-in-one kit is convenient for using.

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 on.
3: The USB SLAVE interface is used to burns the image and cannot be used as an OTG interface.
4: In normal use, it is necessary to provide at least 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.
