No issue at all, just congrats!

That is such an elegant solution, ironically exactly what I wanted to build!
You use INA228, you use ESP32-S3, you use Kicad.. heaven!
Found you through PCBway :)

I read something that might be interesting for you: Instead of using a single 14-bit PWM signal and LPF to control the FET-OPamp, you can instead have two or more PWM signals with different Filters wired in parallel. Imagine one main PWM with R = 1 kOhm and one auxiliary PWM with R = 10 kOhm. You can then use the auxPWM for fine tuning while maintaining high Frequency and good response time on the main PWM. Good luck!

Thank you!

That's good idea! I will try it with using unoccupied GPIO pin.
