DF Robot PiTray for Raspberry Pi Compute Module 4

The PiTray mini is a Model B carrier board for building cluster with Raspberry Pi Computed Module 4 (CM4). PiTray mini focuses on providing a neat and budget solution for CM4 applications. With the same outline and mounting holes with Raspberry Pi Model B, it can be stacked upon the existed cluster.



The CM4 has some advantages over the Raspberry Pi 4B in industrial applications. since CM4 provides models without wifi and Bluetooth chip, the new cluster would be more efficient in energy consumption, the O/S could disable these modules to save its computing resource. What cluster builders look for is a minimal layout with solid module mounting with powering and Gigabit Ethernet which the PiTray provides.

Moreover, PiTray mini acts as a good starter kit for CM4. For CM4 variants with eMMC, there is an eMMC boot switch on board that just makes it a lot easier to flash operating system images to eMMC, so there is no need to spend time to figure out which pins should be connected. It also includes a micro SD card socket to support CM4 Lite (without eMMC and requires a micro SD card).
