uConsole IO & Ports

The IO for the the uConsole seems a bit… odd.

  • Two 3.5mm headphone jacks (with modem)
  • No data on USB-C
  • USB-A is 2.0

Kinda seems like the IO nerfs the CM4’s capabilities.
Any chance these will be addressed before production or in future updates to the main board?

the DevTerm has more USB ports (3) then there is the ‘expansion port’ which I won’t touch … working toward networked devices rather than physically connecting them… haven’t tried the blue tooth but that might work better…

i plan on making a 3d-printed attachment for the uconsole to add some more ports — a couple USB-A, a couple USB-C, RS-232, full size HDMI, ethernet, and maybe a couple others


will an off the sheilf Mini PCi-e card plug into the port where the modem goes? they make single slot USB cards… wondering if that will work for another USB…

i don’t believe so. IIRC the mini pci-e slot used for the cell modem isn’t actually used for the signals of PCI-E, it’s just the same physical connector (probably because it’s cheaper to use an existing connector with enough pins rather than describe and manufacture a purpose built connector, which could increase both complexity and cost). i’ll check whether i’m right and get back to you

edit: yes, from what i can tell i’m right.

the extension module interface is described as “using [the] standard Mini PCI-E connector”, not “being Mini PCI-E”. to me that sounds more like just using the pins / connector, not actually being compatible with other mini pci-e devices. i’d assume they’d say something like “internal Mini PCI-E interface for extension modules” if it was compatible with mini pci-e. :stuck_out_tongue:

Thanks guys!!! Was wondering what to do with that blank slot

No data on usb c? That seems very odd. Where did you find this spec?

Website says it’s a charging port. Might only be hooked to the battery module.
Looks like it’s device only on the devterm, which uses the same board.

It says usb c charging, but there’s not the word “only”, so I thought it was charging and data. It looks to me like a waste to use usb c only for charging


If they’re gonna have a charge port that’s not a barrel connector, i’d prefer USB-C to microusb… Just because that’s what the most chargers littered around my house use


I picked up one of those Anker brand USB-C chargers, it is tiny but good to 20 watts. I use it with the DevTerm and it works just fine. I think it is called the Power Port III Nano.

I think it’s the a04 and a06 that work as a device. The pi4 USBC is power only as well I think.

Cool; I ordered mine with r01, but i may pick up an a04 or a06 as a spare core in the future – i’m very excited to play with a riscV machine, but i’m concerned performance is gonna make it not usable beyond a little experiment…

keep us updated! I’d be interested in buying that RISC-V core and running a terminal based OS on it. Just using programs like Vim, htop, fdisk/dd (to use on USB’s plugged into the device), etc etc. Try writing my own simple programs!

I think for terminal use the R-01 will be fine – it’ll make a great machine to tinker around with vim. I’m just wondering how far i can push it! I’ll definitely stick around here :wink:

I haven’t seen numbers on power consumption of the R-01 part vs the others. I can deal with lower performance if I gain battery life.

I saw a huge battery life difference (+40-60%) between the CM3 and the R01 cores on DevTerm.
