@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.

@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 It worked
I did get something else, more on that later
@loaffette said in Vesc Conversion Status (Rose/Mika):
I managed to obliterate my motor cable on my Superflux
Oh.... wow!
Sorry that happened but dope you got a new cable for free.
Fingies crossed it all works again so you can go clear out them lungs with some zoomy zooms.
WELL
I managed to obliterate my motor cable on my Superflux

I don't want to talk about it
Convinced Fungineers to send me a new motor cable for free, and it arrived on Friday of last week
Spent about six hours yesterday doing the cable swap
I'm tired, I still have a headache from that and I'm very sure the lead content in my body has gone up by a considerable amount
It's not pretty
I will go back to clean it up
I'm tired, I don't want to deal with it for any longer than I have to
@cw_o Welcome :)
If the price is okay I'd take the risk. Getting actual chips from companies like Mouser, Digikey and LCSC can be pricey once you get to the shipping screen. I've gotten chips from eBay and AliExpress (likely the same source) without many issues for things like IMUs, Mosfets and a handful of logic ICs.
Get multiple though just in case you need to redo it. No more than 5 should be fine. IMU's are fragile so you may need to try a few times.
Before powering on I recommend grabbing a multimeter and checking the voltage rails and some of the capacitors for shorts to ground. The caps should have 1 to ground and the other to data so if any are bad then you may have a bridged solder joint under the chip and will have to repeat the process with less solder.
Below is a reference for the traces in the area if it helps at all.
@cw_o Did the seller say what hardware revision it was. It looks like it's pre-serialisation but the 4210-4213 models complain about mismatched BMS's. It can be worked around with additional modding but it's a factor.
4206-4209 are fine so if it's one of those it'll be a simple swap.
