Another small update: Re-added the low-frequency crystal, and adjusted the crystals to match the specs from the nRF52833 reference schematics.
The latest version has been uploaded to https://codeberg.org/whitelynx/lynx-mouse . It currently requires a nightly build of KiCad.
If nobody sees any issues with this, I'll probably submit this version for manufacturing tomorrow.

Latest PCB designs for the Lynx Mouse!
I switched from the PMW3389 to the lower-power PAW3395, and reworked a decent amount of circuit and layout work. (turns out I had some glaring issues in there around the sensor's pins)
I think this version is finally ready to send to manufacture! If anyone here has time to take a look, I'd appreciate more eyes on this.
I won't get the boards back for my birthday, but hopefully I can get the order placed before then.
Finally have a panel of PCBs put together so I can get quotes. Wish me luck!

Well, this is much, much better now. I just need to figure out why my v-cuts aren't showing up, and why it's rendering that empty "moat" around the boards.
I think that's enough for tonight, though, since I need to get up in 4 hours.
I've been designing PCBs for a while, but this is my first time ever designing one with any sort of battery charging or antenna connection. I hope I managed to do a decent job, but if anyone has more experience with either and feels like taking a look at my PCB/schematic, it would be greatly appreciated!
