VOXL 2 Mini not booting...LEDs on and whirring noise
-
My VOXL 2 Mini does not seem to boot. I am powering it directly from a 3.8V lab power supply connected to the J1 power connector. This method was working well for many weeks.
Recently, the VOXL does not seem to boot up. When I turn on my supply, I see the VOXL draw a steady ~1.1A @ 3.8V. I hear a whirring sound coming from the board. The power good LED D1 is steady on, and so is DS2 (green). Any ideas? -

I captured the following on a thermal camera:
The dark red is U10, the other red component is U5.

Hi @serviceberry
I happened to stumble on your post here, sorry it looks like no one ever responded to you.
Is your HW still in error?
Can you confirm how you are powering the VOXL 2 mini, and if anything changed before this issue?
The two ICs you show that are smoking hot are interesting.
The one at 156C is the level translator for our I2C bus on the power connector.
Are you sure you have pins 1 and 2 as power, and not pins 3 & 4? If pins 3 & 4 were accidentally used to power the VOXL 2 Mini, this chip would indeed see the brunt of that issue.
The other chip heating up may just be secondary due to the other failure since that chip is downstream of this one for powering the board from the voltage impacted.
Looking forward to your response and sorry again no one responded (or did you submit a second case??)
Thanks!
