If flashing of OS is required, set the nRPIBOOT microswitch according to the label. For falshing an OS, please refer to the following guide:
https://www.waveshare.com/wiki/Raspberry_Pi_5#How_to_Use
If the CM5 is already flashed with OS, reset the switch to opposite side.
For easy interaction with the OS, insert an USB-C adapter to install the dongle for mouse and keyboard.
Please note that the latest Raspberry Pi OS supports the pairing of bluetooth mouse and keybord at the first boot, so the dongle might not be needed.
For testing the fan, just connect the cable. Be sure that the polarity of the wires corresponds to the lable:
"T-P+"
T: tacho
-: GDN
P: PWM
+: VCC
If testing of SSD is required, intall an "M" key 2230 unit, and secure it with a M2 screw. Some operations are required to flash/mount the SSD, please refer to this guide:

For camera testing, please install an official Raspberry Pi V3 camera module according to the pictures. Drivers should be already present in the latest OS.
This camera test will use Raspberry Pi V3 camera module based on IMX708.
- In terminal, edit config.txt file:
sudo nano /boot/firmware/config.txt
- add the following into the [cm5] section
dtoverlay=imx708,cam0
- reboot
- use the following to check the camera in the list of available cameras:
sudo rpicam-hello --list
For further info about camera interfacing, please refer to following guides:

Connect a screen with a HDMI cable.
Power up the system by inserting a USB-C cable in the USB-PD labelled port. Ensure that your power supply is capable of delivering sufficient energy to the system.
The CM5 should start right away, without the need to push the PWR button. The two LEDs labelled "PWR" and "ACT" will firstly stay ON, and afterwards start blinkinig. The ACT LED will blink as a result of interan operation.
The OS starts showing the Desktop. Test mouse and keyboard for correct functioning.
A pop-up will appear after pushing the PWR button, showing three options:
- Shutdown
- Reboot
- Log-out
If PWR button is pressed for some seconds, the system will shut down automatically.
If the microswitch on the bottom side is set to the nRPIBOOT position for flashing of the OS, power consumption is about 0.035A.
If the switch is not set to the nRPIBOOT position, the OS will start, with a power consumption of about 2.5/3.5A, depending on the tasks the CM5 is performing.
