Power Profiler Kit 2 connection to Thingy:53

[jagerke11]

How do you connect the Power Profiler Kit 2 to the Thingy:53 via the Nordic Thingy:53 current measurement and debug board?  I have been unable to find the documentation on this.

Hello,

Check out this section from infocenter:

https://infocenter.nordicsemi.com/topic/ug_thingy53/UG/thingy53/hw_description/current_meas.html?cp=15_2_3_10_4

I must admit that I have not tried it, but you should be able to measure the different parts of the Thingy using the expansion board.

Best regards,

Edvin

Could you give me an example of exactly how to hook up the hardware to measure the 5340 on the thingy:53?

You need to use the P2 connector on the expansion board.

Use the PPK in ampere mode. Please refer to this drawing:

From the section: "Measuring current in Ampere mode"

Connect the GND to the GND on the expansion board. Then take the VOUT from the PPK2 and connect it to the "top" connector on P2 on the expansion board (top connector when "P2" is written the correct orientation). Then connect VIN to the bottom connector on P2 on the expansion board. Then you can use the PPK to measure the current on the nRF5340 on the Thingy.

Best regards,
Edvin
