We can also transition to USB C maybe:

USB C connector just using usb2.0 pins, should be possible to solder by hand 🥳

I checked the following points:

• Remove Temp Sensor
• Replace wrong screw terminal
• Add additional C10 to OE of U5
• Redo Power Part
• Pin 2 provides the output current and should have a thicker trace. Pin 4 provides only feedback:
  
  
• Redo PCB
• The silk screen is not yet adjusted to the changes
• The microphone board may be a bit to close to the capacitors.
  
• Switching between two copper line widths on the 3.3V line?
