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.

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.

SIM7600 M.2 module

Status of M.2 indicators:

M.2_NET	M.2_STA
Red LED	Green LED	Status
Solid	OFF	Power OFF
Solid	OFF	Starting
Solid	Solid	SIM card is an invalid or weak signal
Solid	Blink	Working
OFF	Blink/Solid	Shutdowning

Before you configure the SIM7600 module, please make sure that the module is started normally.

sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2

Type the following command on the minicom

AT+CUSBPIDSWITCH=9011,1,1

Close the minicom and configure usb0

sudo dhclient -v usb0

About RNIDS networking, please refer to [Raspberry Pi networked via RNDIS RNIDS Networking method]
With the operations above, a USB0 port will be recognized.
If the network cannot work, please try to switch frequency with the following AT commands:

 AT+CNBP=0x0002000000400183,0x000001E000000000,0x0000000000000021
 AT+CNBP=0x0002000000400180,0x480000000000000000000000000000000000000000000042000001E200000095,0x0000000000000021

AT Commands

If the network cannot work, plaese check module with AT commands

sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2

Common AT commandsni

Command	Description	Return
AT	AT test	OK
ATE	ATE1 enable echo ATE0 disable echo	OK
AT+CGMI	Check manfacture	OK
AT+CGMM	Check module type	OK
AT+CGSN	Check SN	OK
AT+CSUB	Check module version	OK
AT+CGMR	Check firmware version	OK
AT+IPREX	Configure hardwara baud rate	+IPREX: OK
AT+CRESET	Reset module	OK
AT+CSQ	Check signal quanlity	+CSQ: 17,99 OK
AT+CPIN?	Check SIM status	+CPIN: READY
AT+COPS?	CHeck the current supplier	+COPS: OK
AT+CREG?	Check network status	+CREG: OK
AT+CPSI?	Check UE information
AT+CNMP	Configure network mode： 2：Automatic 13：GSM only 38：LTE only 48 ： Any modes but LTE ... ....	OK

PCIE

The PCIe interface is PCIe 2.0 X1, the maximum speed is 500Mb/s
Most of the PCIEx1 device is not supported by Raspberry Pi without a driver.
Please check your PCIe device before you used Supported device testing
