STEMLAB 125-14 only orange LED on

Post by rdubroeu » Tue Aug 31, 2021 5:46 pm

Hi everyone,

So i was using a STEMLAB 125-14 and feeding a sine wave output to a AD620 amplifier (I want to amplify the Redpitaya signal from 2 Vpp to 10 Vpp at least).

But after some time, the board stopped working. Now there is only the orange LED, all the other ones are off.

I didn't match the output impedance of the board to the high input impedance of the AD620.

Did I just kill my board because of an impedance mismatch ? Could the reflection do that ? The signal generated from the board at the time was a sine wave of 1 Vpp and 1kHz.

Thanks for your help !

Unfortunately that is a possibility however to make sure,
Please let me know if the issue is manifesting after you manually update the Red Pitaya OS to the latest BETA by using this guide:
