Pinecil V2 happily negotiates and accepts 28V via USB-C PD...
Describe the bug
When plugging the Pinecil V2 into a USB-C PD power supply that outputs not only the typical voltages like 5V, 9V, 12V, 20V, but also 28V, the Pinecil V2 happily negotiates 28V. I have no idea if this negotiation is done by IronOS or by some hardware... but if it is caused by IronOS it would definitely be worth fixing!
To Reproduce
- Buy a USB-C PD power supply that also supports 28V (in my case a VC-C909 power bank), and a USB-C cable that supports that voltage as well (like the one that comes with the VC-C909)
- Plug the Pinecil in
- Watch the power supply display "28V" and the Pinecil "26V"
- Unplug it
- Plug it into a power supply that normally works and watch the Pinecil simply turn off as something's now broken(?)
Expected behavior
The Pinecil should negotiate 20V, not 28V, as 28V seems to have been too much for my tip.
Details of your device:
- Device: Pinecil V2
- Release: v2.22E
- Power adapter being used: VC-C909
Additional context
If you need more info please comment
I have basic soldering skills, I know how to attach a Pico for USB UART, and I even have a cheap logic analyzer, so if you give me instructions I could probably assist debugging this on my own iron.
Update: Some have claimed only the tip may be defective. I wonder if that's true. Update 2: That tip measures 0 ohm. So looks like only my tip is gone!
For documentation purposes, it was the tip that comes with the pinecil v2. According to IRC discussions, it's the EPR feature that should be disabled by default in the future.
I've been using my Pinecil v2 at 28V (Apple PSU) for pretty much a year. No issues at all, just benefits.
It truly must be a defective tip.
me too. no problems at 28V. this is optional. people can still use plain old 20v if that is their comfort level. power users who don't mind things breaking sometimes like options to push boundaries.
