X-NUCLEO-IHM08M1 schematic question

luke514 · ‎2026-05-26

I'm looking at a diagram of the X-NUCLEO-IHM08M1 and the manual states that you can select either 1 shunt or 3 shunts using jumpers J5 and J6.

By default, there is one shunt, but when tested with a multimeter, there is continuity between the two red points in the photo:

With the multimeter, I should be getting a reading of 10 MΩ on the tin, right? And between the tin and the other plate?

At a glance through the schematics of the X-NUCLEO-IHM08M1, you will find on J6 (similar for J5) the two signals Vshunt_2 and Vshunt_3, each of which leads to a shunt with 10mΩ. All of these shunts are connected to GND, so you should measure 20mΩ between the signals - which ordinary multimeters usually cannot distinguish.

Hope that helps?

Did you mean MΩ - or mΩ ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
