Nordic PPK2 - Updated Power Profiler
exe:
My ppk2 collects dust. I bought it just because I was worried about availability in the future. I can give you mine for a month, if you want.
Radiohead:
Thanks for the offer, but I have a PPK1 available for testing.
I'm just curious what people's experiences are and whether it's an improvement to pick-up later on.
whims:
For the price, it's worth the wait. If you don't care about pricing, I guess there are better tools around but I am using my PPK2 all the time. Not too much for reviewing battery lifetime but for timing and having an adjustable power source.

Hello everybody.
Sorry for reactivating this old thread. The hardware is practically open source. Do you think it is feasable to modify it to have a range of a decade lower?
I only need 100mA for the highest current but 10nA resolution in the lowest range.
Tweepy:
Sure, the hardware schematics are available (not open source), but not the device's firmware source code. I don't see how you could change theses ranges (resistor values?).
The desktop app is available here: https://github.com/NordicSemiconductor/pc-nrfconnect-ppk
That's definitely a pity the device is not more open, either the interface or the firmware, at this price point (80€), with the 0.8V-5V power supply, it's definitely a great tool for any embedded developer, and a must have for any battery project!
Look like NRF recently updated the Power Profiler app (from nRF Connect) with Version 3.1.1 and new features (screenshot attached):
- CSV export
- real time vs data logger mode
- trigger mode (on current, not logic input) with pre and post trigger buffer
- adjustable sample rate
Now that most distributor have it in stock as from Q2 2021, has anyone anything to say about it, used in real projects?
