TF card interface: used to access TFcard with system, only for Lite version
HDMI1 cable interface: HDMI1 interface, supporting 4K 30fps output
USB 2.0 cable interface: USB 2.0 cable interface, which is connected through the adapter board
FE1.1S: USB HUB chip, USB interface 1 expanded by 4
M.2 interface: it is suitable for NVIE solid state disk or communication module supporting PCIE M.2 interface
Precautions for use
1. Fan fans only support 5V fans. 12V is not supported. Confirm the fan voltage before connecting. This version of fan has no controller and can't adjust speed.
2. DSi display interface is dsi0 interface, but dsi1 display interface is not connected.
3. Type C interface can be used as power supply or USB slave interface to burn image.
4. In order to ensure the normal power supply of CM4, please do not connect other devices when using type C interface to burn images.
5. When CM4 is in normal use, it needs to provide 5V 2A power supply for CM4. Otherwise, problems such as automatic shutdown and frequency reduction may occur.
6. When using the m.2 interface, please use the matching screws. Using screws of other lengths may cause the CM4 core to be damaged by screws.
7. The module does not have any protection. Please do not short circuit the power supply.
8. USB2.0 is closed by default. To open it, you need to add dtoverlay = dwc2, Dr in config.txt_ mode=host
9. HDMI1 uses flat cable output. If you need to use it, you can buy another HDMI-Compatible adapter
10. Yes, USB 3 / 4 and hdmi1 can be connected by adapter board
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
