Hi!

I noticed a constant weak audible clicking sound (each measurement triggering time) from the boost converter. Can this harm the circuit during long term usages?

This is how the signal looks for a 500ms trigger time:

Thanks in advance!

Hi Thibault,

Where is this signal that you're showing? Is this the TX output?

I would not be concerned about the sound.

Hi Scott Cummins,
It's the 30V power supply from the boost converter.

Okay, so the implemented boost converter is durable for these kind of "mechanical" vibration from the inductor?

Thanks
