I use

* 1 CM4 for a PiKVM on my desktop (my main home server uses a proprietary iLO).

* 1 CM4 as router running OpenWrt, to replace my ER-Lite.

* 3 CM4s in a Turing Pi 2, one Jetson Orin for ML. This is my homelab. The CM4 are running Dietpi.

* 2 RPi4 as remote VPN (Wireguard) endpoints to do tech support for my mother-in-law and mother. Also serves as Jellyfin server containing old movies, and jumphost for NAS backup.

* 2 RPi0 2 W with Enviro+. One indoor, one outdoor (with different, custom 3D printed casings). Runs Raspbian, will switch these to Dietpi.

* 1 RPi3 for with my portable HackRF (with custom 3D printed case). Batteries included!

* 1 RPi0 W for Pwnagotchi. Not really used anymore but too cute to break.

* 1 RPi0 W for Pimoroni grow to track water management in plants (with 3D printed case). Need to get that project moving, it is for my mother.

All my Docker containers run on my main server but I'm considering to switch to my Turing Pi 2. I got solar, so the Xeon is OK for now, but still...

Then I got: 1 RPi3B+, 1 CM4, 1 RPi2B, 1 RPi0 W. I should sell as they're right now 'Raspberry Piles'. Won't use them. To be frank I'd like to upgrade the RPi3 with the portable HackRF at some point, and once I get a 3D printer I might need Octoprint so I suppose I could use one of these machines for that.

CM is the computer module, right? what kind of "board" do you use the CM4 with to use it as a router?


I went with Dfrobot [1] because they also sell a case (and it is all in stock). Had the CM4 already. I wouldn't have minded another one if I could've 3D printed the case but I didn't find such. Btw, I did have to go from 3 to 2 ports.

Right now it is hooked up on my switch. I intend to put it between my desktop and my switch and run some iperf3. Because I'll get fiber soon, and I'd like to be able to saturate that.
