Is the cm4 adapter interchangeable with other cm4 to cm3 adapters? I’ve seen some people talk about this alternative.

I tested it with the waveshare one and it did not work. I have a video of the behavior if you want to see but it essentially just blinked once powered on. Since there were diagrams available I checked the pinout and found that quite a few of the pins were in different locations. Was going to try and buy one of the no-name ones that you see everywhere but my official one finally got here.

I’ve seen 3 variants of the adapter board including clockworkpi’s. Waveshare’s DSI pins are swapped(DSI1\<-\>DSI0), and some pins are missing/reordered. One no-name adapter has no public schematic. So if you want to use CM4 in a uConsole, you should stick with the official one, or use CM4S(and update some kernel code accordingly).

Old thread, anyone have success with a “generic” adapter? Any mods that can be made to make these generic versions work? I’m kind of thinking of this one since it has a schematic for cross reference. [CM4 to CM3 Adapter - Geekworm Wiki](https://wiki.geekworm.com/CM4_to_CM3_Adapter)

Tired of waiting for my adapter to ship so I can upgrade my Devterm.

It doesn’t on the devterm, so I doubt it’ll work on the uConsole.

I did some more reading and it’s a maybe. I have a feeling it is a power supply voltage issue and a data level voltage issue, as well as some swapped things like display0 vs display1. In theory the correct bits are shipping soon for my uConsole and the extra adapter for my Devterm, in theory.
