Does anyone know if the CM5 will be supported on the two released motherboards (2.4 and soon 2.5), additionally will they require new/different adapters than used for the CM4. Thanks

Wont know till it actually comes out

Thanks - I'm expecting that it will 'work' but expect that a new adapter board will be required to allow functionality not supported by the CM4

Yeah, me too

Now it is there…

Since the naked RPi CM5 modules are pretty difficult to get, I've ordered an RPi CM5 devkit. Won't get here until next week, but I'll take a look at it on both the TPi v2.4 and v2.5.

Don't install the heatsink if you want to install the CM5 in the devkit case. There's not enough clearance with the little case fan. See [here](https://discord.com/channels/754950670175436841/754950670645329920/1312580031633035325).

I'll keep that in mind. I thought the devkits shipped with the passive heatsink that is sold separately.

Correct, it's the passive heat sink. I'm surprised they missed this, that you can't use everything that shipped in the devkit at the same time due to this clearance issue.

Yeah, I see now that I received mine. The plastic spacers for the passive heatsink are a joke. I have no idea what the thicker plastic spacers are for. Maybe the Pi 5. The Geekworm CM4 passive heatsink doesn't fit correctly. I had some shorter M2.5 (I think) screws that I used to fasten the CM5 passive heatsink. Should be okay. I generally use an older/old Windows 10 Thinkpad to flash compute modules. Forgot that the Windows USB drivers for BCM2711 and BCM2712 aren't signed, and so won't automatically install. Flashing RPi CM4 and CM5 with eMMC is something to add to the Turing Machines' documentation. I'll probably do a Forum post first, then follow up with an FAQ that can then be expanded and merged into the doc.

The Amphenol flat connectors to which the ones on the CM5 connect come in two sizes. The IO board has the shorter ones. But you might want to install the CM5 in a board with the taller ones. Hence two sizes of spacers.

Will it work on the TP CM4 adapters and also provide M.2 access?

No. The CM4 adapter routes the single PCIe 2.0 lane on the RPi CM4 and RPi CM5 to the node 1 and 2 mPCIe slots, the node 3 SATA controller, and the node 4 USB 3 controller.

So will we be seing a new CM5 adapter then to also be able to use them?

The RPi CM5, at best, partially works. Haven't finished basic functionality tests (https://discord.com/channels/754950670175436841/1311437734308479016/1315730253544689685). I'll keep updating this post. If you want to experiment, I would NOT purchase an RPi CM5 with eMMC without the complementary RPi CM5 IO board and power supply. The RPi CM5 developer kit is the easiest way to obtain this configuration It remains to be seen whether the RPi CM5 Lite (without eMMC; with SDIO) provides similar, but also partial functionality, when mounted on the Turing Machines CM4 adapter.
