 All right, Leida, what is this? You might say, hey, you should get a clue, but you should get two clues. And this is actually a revision. So this one, you see here, it's got this square LSM6DS33. That got discontinued. So this is the LSM6DS3TR, which is very similar, but not quite identical gyro accelerometer. So I revised this board to now use this part. And pretty much all the other components are the same as I think the flash chip also changed. And then I updated the test software. So this is the old test program. This is the original clue that's in the store. Passes tests, good to go. And then this is the new version with the updated code that now looks for the LSMDS3TR, also passes tests. So both are good. This revision, I'm going to order it and we'll get it into the store. It's been out of stock for quite a while, so I'm very excited to see this part back in stock. We were clueless? No, we're not. Yes.
