Title: UM34C: are the USB "UM34C" ammeters all of the same quality?
Post by: eti on October 23, 2022, 01:33:20 am

Hi all. My friend is looking at these mini "UM34C" mini usb ammeters, and wondered if there's any diff in quality/performance? The prices seem to vary from ~£30 to ~£100+

Many thanks.

I would guess that it's almost guaranteed.

Get the fancier version that supports USB PD commands and USB-C passthrough, great debugging tool for testing random USB PD devices.
