This is Raspberry Pi CM4 IO Board Server Rack mounting bracket. I created it for my own server rack.

This bracket has following features:

• CM4 IO Board compatible with all front IO ports accessibility
• OLED (0.96") mounting position (put the OLED screen into designated position and using soldering iron melt printed studs to hold the OLED PCB in place)
• Additional hole for button (a screw on)
• Access hole for the CR2032 battery
• IO Board mounting holes are foreseen to be fitted with brass inserts (by melting them in with a soldering iron)
