<Armbian-Discord> <l​anefu> yeah as far as I know.. PBP as always been 5V
<Armbian-Discord> <T​onymac32> That is 100% dependant on the support circuitry, nothing to do with the SoC
<Armbian-Discord> <T​onymac32> OK, you'll burn your PBP to ash 😄
<Armbian-Discord> <T​onymac32> I can run USB type-C power delivery with an 80286 as long as I can talk to the port controller and have a buck/boost converter as needed
<Armbian-Discord> <T​onymac32> ok now I want to make a DOS-only SBC with type-C PD
<Armbian-Discord> <T​onymac32> ohhh yeah
<Armbian-Discord> <l​anefu> I support you Tony
<Armbian-Discord> <T​enkawa> I know this.. let me be more explicit then if we are nitpicketing then... What's the "support circuitry" on the PBP's full specs?
<Armbian-Discord> <T​onymac32> It has none, it's just 5V from what I can tell. I'm not nitpicking, I'm making sure no one unfamiliar with this tech reading this chat run off with some unfortunate ideas about SoC support for something like type C power delivery.
<Armbian-Discord> <T​onymac32> You did specifically say the RK3399 might be too old after all
<Armbian-Discord> <M​anoftheSea> did you say you'll be putting a supercap on an SBC to weather the odd power renegotiation without rebooting?
<Armbian-Discord> <M​anoftheSea> Well, I can dream.
<Armbian-Discord> <T​enkawa> Even current readings is it can't get a full 5V...
<Armbian-Discord> <T​enkawa> This thing has a very weak delivery circuit
<Armbian-Discord> <T​enkawa> 4.96V or so
<Armbian-Discord> <T​enkawa> so I definitely agree with the easily toastable thought just watching "default" settings
<Armbian-Discord> <T​enkawa> Oh well.. At least it works
