  • USB-C to USB-A cable.
  • HDMI cable.
  • Straight Ethernet cable (for the ATX board connection).
  • Power supply unit (5.1V 3A USB-C, recommended by the Raspberry Pi).

Basic setup

1. The SD card preloaded with the factory default image does not require burning. If you need to reflash the system or for DIY purposes, you can followFlash the memory card or eMMC

2. If you have a non-plug version, refer to the video and instructions below for device installation:
1. Use the provided screwdriver to open the metal casing and remove the PCB motherboard.
2. Install the CM4 onto the PCB motherboard, ensuring that the two rows of card slots are aligned. Apply the thermal conductive silicone pad onto the CM4 main chip to facilitate heat dissipation using the metal casing. The fan is not connected by default as the metal casing provides sufficient heat dissipation. Depending on your CM4 version, selectively install the Wi-Fi antenna.
3. Reassemble the PCB motherboard and the metal casing to complete the installation.
4. Please note that translations might vary depending on context and specific terminology used in technical instructions.
