Jumpered to boot from R Pi... - BaconRanch - 08-13-2024

Hello,

I changed the jumper to boot from USB C port on CM4 Raspberry Pi and its not booting, no pwer at all in either position.  Please advise what else needs to be checked.

Thank you,
Mark @ Bacon Ranch

take a photo how you set. it's better take a video of your problem.

It seems like there are only a few options for a jumper, why not just tell us ?

None the less here is another video I have had to make, download, and then upload and share

Please take the device back for a refund.

My understanding is that the board needs 12-24V to operate. Are you sure the board is supposed to also be powered via USB-C? The relays need 12V to switch, I don't see the USB-C connector providing this.

I had asked this and was told yes....I have a few R Pis running Home Assistant instances and they all power via USB C .  The power supply I am using is designed for R Pi4 and does provide 12V and 2  amps.    The jumper apparently is for this purpose but its only 3 pins so it can only be 2 positions or a 3rd option I suppose is no jumper ?

Cheers

Raspberry Pi 4 is powered at 5V. If you have a power supply that works on a RPI4, it has to be 5V, and I doubt it will power the Kincony board.

thats right, I meant 5V 2A....wish this information were easy to find though, didnt think I could put 12V into the R pi USB c ?  Probaly what it is though.

Thanks again

Server16's USB-C use for read/write SD card (if CM4 without eMMC). Not use for power the board.
Server16 need DC12v power supply to work.
