Writing Image

USB2.0

The USB interfaces are default disabled in CM4, you need to enable it by adding the following lines:the config.txt 

dtoverlay=dwc2,dr_mode=host

USB TO UART

The USB to UART port is connected to GPIO14(BCM) and GPIO15(BCM) pins of CM4 with a converter.
You can connect the USB to UART port for login CM4 via serial.
The USB to UART port can also be used for power, in this case, you need to solder a 0ohm resistor to the pad for enabling the powering function.

Buzzer/LED

Buzzer

The buzzer is connected to GPIO22(BCM), low active.

LED

Two LEDs are integrated for users, the green one is connected to GPIO20(BCM)and the red one is connected to GPIO21(BCM), low active.

4G/5G

To work with 4G/5G, you need to connect a wireless module to the M.2 B KEY for featuring corresponding functions. M.2 B KEY only extends USB2.0 interfaces, it doesn't support PCIe devices.

SIM card is required to work with the 4G/5G module
This carrier board supports the 4G module by default, if you use it with 5G modules, some of the 5G functions are not supported.
If you use a 5G module, please check the [SIM8200EA-M2_5G HAT wiki] about how to set up 5G.

4G

If you need to toggle the working status of the 4G module, you can control the GPIO6(BCM), set the GPIO6 to High for disabling the 4G module and set it to Low for enabling.
To toggle the working status of the 4G module, please add delay time for waiting for the operation to work.
