Hi,
We brought the following items on april 2021
-Adafruit RGB Matrix HAT + RTC for Raspbe
-Absolute orient IMU Fusion BrkOut
which is shown in the wiring circuit in the image, .
So after connecting to our Raspberry pi 4, we used our existing code which works for the previous batch we brought long ago, into the new set, however there's an error message on it.
Any advise on this?

Re: Raspberry Pi 4 error regarding to IMU
Can you take a picture of the soldering on the IMU Fusion BrkOut?
If you test one at a time the original Matrix HAT that was working with the new IMU board does that configuration work? If it does, will the reverse the new Matrix HAT with the old IMU board. Just trying to narrow down what component is causing you grief.

Hi thanks for the feedback, here's the soldering of the IMU, And the connection for the IMU to Matrix Hat is this I've also tested the original working Matrix Hat with the new IMU board, and the configuration works. We swapped the IMU board to test with the new Matrix HAT, and it doesn't work.

Re: Raspberry Pi 4 error regarding to IMU
Thank you for the photos.
Soldering looks good on the IMU.
The new Matrix Hat appears to be the problem culprit based on the summary of your testing.
Can you post a photo of the underside of the new matrix hat top and bottom. I'd like to verify the soldering on both sides. You provided a good angled view, but straight above might show some clues.
I see we have revved the Matrix Hat a few times and are currently on Rev. C. One of the things that has changed is the solder E jumper. That is something you can compare between the old and new Hat to see if they are both Rev. C and if it was something you had configured the jumper on the original for.

Also - Had you been messing with the quality pins GPIO4 and GPIO18 on the original Hat?
