Hey guys, I don't know what's going on last week my BMI 160 was working fine on my ESP32 WROOM-Dev kit and then suddenly the chip began to overheat. I wired all the pins correctly, 3.3V, GND and etc. but as soon as I plug power into it, for all the chips they begin over heating. What could be the cause? I'm using i2C if that changes anything and I used this chip for over a year and then tested on 2 brand new ones.

Try connecting it with your device and upload some program check if it still heats up

Introductory Tutorials When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th… [image] rhythm8503: my BMI 160 was working fine on my ESP32 WROOM-Dev kit we also need to know exactly what parts you are using - so eg is this the BMI160?

Post an annotated schematic showing exactly how you wired it be sure to show all connections, power, ground, and power supplies. Also how do you know your 3V3 power supply is giving you 3V3 instead of say 9V. Your description indicates it was over voltage at one point or it is now. Provide links to Technical information on the hardware items you have connected.

I already said screw it since I've had issues with the BMI 160 and just returned it and got an MPU6050 and it hasn't given me issues so far

Thanks for letting us know! :slight_smile:

What changed? Double check your power supply voltage. Sometimes the onboard vregs fail shorted with catastrophic results. What are your voltages?
