Feedback round two!
I like your design of the circuit, well done!
A few comments:
- You might be missing a capacitor between 3.3V and the MCU.
- Add testing points for ground so you can measure over components during the debugging process.
- Adding testing points for the mouse buttons might make the debugging easier down the line.
- Depending on which encoder you've chosen to use, you might have to make a custom footprint.
