BNO0085 modul not working

Post by maciii »

Hi I just purchased BNO0085, I soldered PS1 pad only. After connecting into USB TTL FT232RL board is "dead". No communication, no green power LED. I tested both connectors.

I also have BNO0055 and this works ok.

Here is video https://www.dropbox.com/s/lrynjc5ox9i8l ... d.MOV?dl=0

I purchased both pieces from germany distributor Paradisetronic.com - 8.5.2023.

Can you please help me with this?

Adafruit offers replacement warranty up to 30 days. But I am not sure if they bear any responsibility of products baught from their distributors. Let's hope they will answer and suggest a solution.

The power indicator LED is not even coming on. That much at least should work - same as it is doing for the BNO55.

If you have a multimeter, it'd be interesting to see what voltages show up on the Vin and 3Vo pins when plugged in. There's nothing obviously wrong in the photo, but it's acting like it's not even getting power.

Voltage is 5V and 3.3V - see pictrures. LED could be bad (which is not problem for me) but board do not communicate with me :-(

Thanks for that check. Really weird results.

One other quick/simple check - try the other STEMMA QT connector on the BNO085 breakout. Same results? No need to measure voltages again, just curious if LED comes on and/or coms work?

Yes, same results with different connector on both STEMA connectors - as you can see on video in first post, connector is OK with BNO0055. :-(

OK, let's try a replacement.

Send an email to [email protected] with a link to this thread and your order number and they can send you a replacement BNO085 breakout.
