2021 Onewheel XR IMU model?
-
I am making this post to see if anyone knows the model for the IMU on older onewheel XRs.
I've been working with a graduate student here at my university and we've managed to get the IMU off of the controller however it appears that the chip model I was recommended (LSM330DLCTR) is for a different revision of my board. For reference, this onewheel was purchased in 2021, and I have attached a dropbox with some photos of the IMU as well as what we think the chip could be.
Any information would be greatly appreciated!

@cw_o Oooh yours uses the small one. Are you sure it's an XR? Like when it's powered on does it give a model hardware revision like 42XX?
I only ask because on the older XR models there are 2 spots for an IMU and the smaller one doesn't even use that footprint. Below is a an example of the same area on a 4208.
Regardless the chip you found appears to have the right pinout for the smaller one. The newer 4212 models use the same style IMU just with the blue PCB and complete rework of the layout. 2 pads look to be torn but they're unused so thankfully not an issue.

@lia Yeah I am pretty sure it's an XR, it has the XR rails and says it is an XR in the app. The guy I bought it from also had never opened it before, all factory stickers were intact.
But thank you for your insight, I will go ahead and order that chip and let you know how it all goes!

@cw_o Best of luck with the swap :)
When you do boot it up lemme know what the hardware version (42XX) shows as as I'm actually curious if there was a batch that had the alternate design.
