The power at the battery connector would be unregulated and vary with state of charge. You’re talking about with a battery connected or no? If no, there probably will be no power at the battery connector. Laptop batteries are smart & motherboards communicate with them to be sure they are healthy. Without a battery present, the mainboard will very likely not send any power. Now, Framework being as open as it is, you might potentially be able to mod the embedded controller firmware to provide power anyway.
Wrong direction, that one makes a pd power-supply put out a specific voltage (very useful if you want to charge a non pd laptop with a pd psu or power something taking 20v but probably not what you want to do here).
may have found a fix finally for the power issues CRImier has built an input cover shim to make it a usb a port, so naturally i could use a usb adapter and power breakout to theoretically finally power the drives. will keep working on the case.
Finally finished first revision for the 3d Printed Case Design. While the above mentioned Usb Shim couldnt possibly power 6 3.5" HDD, im back to the drawing board on how to get a 12V rail from some connector. ive figure ill use TrueNas Core as the OS, Running RAID 5 Across 6 4TB drives. The OS will boot from a 256GB usb-c Expansion card from the framework marketplace and my other planned expansion cards are; Ethernet(Ofc), Usb-c For power and possibly either a USB A or one expansion bay will be sacrificed for their 20V rail. I plan to have a front facing usb-a anyway underneath the power button button. all of my planned associated components are accessable through that same GitHub repo.
That’s just the acceptable voltage for the connector’s Vbus contacts. That’s saying that it’s tested for that voltage. The datasheet you linked is just for the specs of the physical connector. It’s not saying that 20v will be present.
USB-C starts off with 5v on the Vbus power pins, then if the device is USB PD power supply it can change the voltage on those pins provided the device connected to it properly requests that & it supports the voltage and current requested.
Iirc the Framework usb ports are not USB PD power supply out ports. They provide only 5v and won’t provide more. This is normal for computer USB-C ports. Their purpose is not to be a supply for a lot of power.
according to Reddit - Dive into anything
people have done 12v to usbc for small 18w applications by soldering the 12v molex to a car charger, i found a pd car charger that can do 100W, theoretically as long as my soldering is clean and covered this should be safe and a good solution. @MJ1 let me know if theres anything wrong with this.
