No AC101 detected (i2c driver not installed?)

Hey,

After spending the time getting this to compile and flash, I'm getting a "No AC101 detected" message in the serial monitor. (I also see "i2c driver not installed" but if my googling is correct this is a non-issue.)

I'm using [this ](https://www.aliexpress.com/item/1005002392615155.html?spm=a2g0o.9042311.0.0.4d444c4dLiRTmb)board which should have a AC101 according to your docs, I've spent awhile trying to confirm but I can not find the relevant documentation.

Does anyone have any guidance on a solution? Serial output below.
