uConsole CM5 mainboard

Better to keep the expansion port as is and retain compability with existing third party expansion cards.
A pci-e connector on the board would allow you to place either an M2 or a PCI-E expansion on the inside and get the best out of two worlds.

As I mentioned in one comment, it will have the same PCIe port like Pi5.
Now I`m working on the Buck/Boost converter for the battery pack to support 1S(original battery board) 2S and 3S configs,selectable with a dipswitch.

Would you be able to add a PWM Fan header, or expose some of the unused GPIO?
That, and the Ethernet FFC would check off everything on my wish list.

Really great job doing this.
I think i speak for a lot of us in saying that no matter how you go about releasing this when youā€™re done iā€™ll sure as hell be getting one.

One good expansion to do on the board might be a USB-soundcard since i understand thereā€™s issues with getting audio from the CM5 as compared to the CM4.

The raspberry pi cm5s audio is fine. Itā€™s the radxa cm5 that has no audio.

Oh sweet, misunderstanding on my end there.
Good thing thatā€™s not an issue.

Ethernet would really be nice. Honestly in recent times its been the most wished for port for me at least. I"m fairly sure many other uconsole enthusiasts share my sentiment :slight_smile:

Could have a dual 2.5 lan port or single lan and a bunch of usb, dual hdmi , dual m2 and everything normally found on a dev io.

Lan port is one of those things that are nice as an expansion, if you want lan get a lan-expansion card and since itā€™s something thatā€™s pretty seldom used these days itā€™s better to just carry a dongle.
Sure i can see the professional usecase where a sysadmin can whip out his uconsole and plug in to some router but in most cases thatā€™s a fantasy usecase since itā€™s more and more common that private devices are barred from connecting to the networks for security reasons.

Better to just see if this project comes to fruition and he manages to make the device he wants instead of bogging it down with a mile long wishlist.
If thereā€™s something we want to add we can do it through the expansion port, via dongles or using the usb3 or pci-e on the inside do add functionality.

I would replace USB-A with a second USB-C

exactly you have to have a cable attached anyways so an ethernet dongle really isnā€™t a big ask, unlike say a SDR. Biggest improvement I want to see is a beefier power rail for cm5, PCIe and USB3. Weā€™ll never get USB-C altmode displayout as the rp5/cm5 soc doesnā€™t support display port. This is also why Raspberry pi went with HDMI mini vs USB-C on the RP5.
