raspberry power
Is it possible ?
If I connect my rasp directly via USB to the Octopus for alimentation ?

I've heard that people have successfully powered the PI via the USBC port, something about enabling OTG in the boot.txt, I have NOT been successful, however I AM directly powering my PI off the 5V UART header on the octopus to the 5V GPIO.
You don't have to do anything special to power the pi from the USB C port. You can either use a separate 5 v PSU or use a buck converter to power the pi.
I think he was refering to powering the Pi from the USB-C Port on the Octo to the USB-C port on the Pi, I've heard of it being done. I havent had any luck with it.
Atleast thats how I understood the question.
I do believe the 4 supports OTG on the USB-C.
Ahh I see, I misunderstood then. From what I understand powering the pi from the octo is not very reliable. I went with a buck converter personally but I can understand why OP wants to power it from the octo
I can't vouch for that, I'll attempt again on my rewire, but I couldn't get it to work personally, Hence why I opted for the 5V rail from the board itself. Supposedly, the board supports 5A on the 5V rail, so it shouldn't have an issue pushing the 3A over USB, I planned on poking at it again when I go to rewire the electonrics. Hoping I can 100% confirm/Deny

I would consider this a bad idea, might cost you some failed prints. Just use dedicated PSU (rs25), or good buck converter with low pulsations or just 5V rail on octopus to gpio pins (but use 2 cables as in the docs)

Hi,
the problem is that the GPIO power supply is below the 5V of my RPI. So I think I will opt for a voltage converter taking into account the recommended amperage..
What are you using to power at the GPIO currently?

Yes and i have 4,53V with this config

Just two wires of 24AWG?

I'll tell you this again when I get home
