Nordic PPK2 - Updated Power Profiler

(1/6) > >>

Kean:
Nordic have released their new Power Profiler Kit II at about US$90.  https://www.nordicsemi.com/Software-and-tools/Development-Tools/Power-Profiler-Kit-2
DigiKey have some stock, but are selling out fast.  Elsewhere it is backordered anywhere from a week to 3 months.

It can measure in 4 auto-switching ranges from 100's of nA (resolution, not FS) up to 1A, sampling at 100 kSa/s.  It can act as a programmable source 0.8V to 5V (with boosting from USB power), or just as an in-line current sensor (still limited to 5V 1A).

One neat thing is that it have 8 digital inputs that can be used as a simple logic anaylser for correlating system state with changes in current draw.

It is worth noting that it cannot measure reverse current (i.e. battery charging), and also is only specified for +/-20% accuracy.  That is worst case I guess, and should generally be better.  It even has some internal calibration shunts.  And while the firmware is apparently closed, the host application is open source and thus so is the communications protocol if you want to extend/rewrite it.

It is not quite a Joulescope in functionality (actually a long way off), but reasonably low cost and quite compact.  I've ordered one to carry in the backpack.

Kean:
Oh, and the schematic and Altium design files of the PCB (Nordic PCA63100) are also available at https://www.nordicsemi.com/Software-and-tools/Development-Tools/Power-Profiler-Kit-2/Download#infotabs

Interesting, U2 doesn't have type/name on the schematic. I'm on the edge if I want to buy it. I'd like to play with it, but not now. But leading time of 20 weekds and bad availability make me thinking if I should buy it now.

If you view the schematic in Adobe Reader you can click on a part to get the full details including Digikey & Mouser part numbers - it's an ADA4622.

Kean:
Well Digikey has now sold out of their initial stock, and Mouser website says they expect stock arriving mid March.
Nordic did say during the launch webinar that European distributors should be getting stock soon, so presumably there is more stock working its way through shipping channels.
