Just a reminder that if you use the USB Tester with a newer phone with quickcharge you will need to cut the solder jumper on the backpack. This stops the quickcharge voltage from hitting the USB Tester which can be up to 20V. Its a simple process to cut the trace. Just remember that the backpack will now need its own power 5V supply via the USB connector which is the same as data logging.

More information will be kept updated at

USB Tester and Quickchargers

Do you have a photo of the trace to cut?

I have updated the picture in the post linked above. It now shows where to cut with a red link and zoomed in.

Thanks.
