PPK2 showing crazy current even if it is OFF

[zyghom]

Just see the screen shot - PPK2 is OFF yet it shows 200mA

Hi there,

Can you specify what you mean by the PPK2 is OFF? From the screenshot I can see that you have connected the serial USB cable to the PPK2 and have enabled the power output.

Hi Jared, are you saying 11 Amps is what PPK2 can deliver? and max 22A?

[Jared]

No, that's not what I meant. I agree that the numbers in your plot seems unreasonable high. But I'm trying to get a better understanding of your setup. How is the PPK2 connected to your computer and is anything connected to the PPK2?

this app used to work flawlessly, then the upgrade happened (I am on 3.5.2) and the issues started.

See below the mac info.

Connection: usb-c to usb-a cable (official apple one) then PPK2 (a bit of shame the PPK2 still uses micro usb)

I'll check with the developers if there is anything in the new update that could cause this.

Is the PPK2 connected to anything other than the computer? Is it connected to a DUT via Vin or Vout? Could you take a picture of the PPK2 that shows how it's connected and upload it here?

thanks,

o yes, of course

micro USB: "power plus data" connected to macbook

Vout and GND connected to my ESP32

PPK2 used as a source of the power for ESP32

no other pin connected on PPK2

Hi,

Can you share the revision and build code for your PPK2? You can read it of the sticker on the PCB.

Hi Zygfryd,

Could you disconnect the ESP32 from the PPK and only connect it to the Macbook. Are you still measuring unreasonable values when it's not connected to anything except for the Macbook?
