A raspberry pi cm4 board with integrated gigabit switch.
Two CM4s and three RJ45 Jacks each connected to a Microchip KSZ9567
In the future I will make a board with four CM4 modules and one RJ45 on the switch, but for now I am making this so I can test the switch on its own.
However this also makes for an interesting board in its own right, as two wifi CM4 modules could make this an interesting router board.

The Raspberry Pi CM4 is a product of Raspberry Pi (Trading) Limited.
This Raspberry Pi CM4 switch board was forked from Alexander Rau's rpi-cm4-LiM-board: https://github.com/l00nix/rpi-cm4-LiM-board
Alexander Rau forked the rpi-cm4-LiM-board board design from Shawn Hymel. Shawn has a two part youtube series on how to design a CM4 Carrier Board.
