STM32 PCB Layout Review & Fix

My compact STM32 board (15–20 parts, a mix of SMD and through-hole) is almost there, but the power rail and trace layout still feel sloppy. The project is in KiCad and intended to sit in a mikroBUS socket, so I need a fresh set of expert eyes to make it rock-solid before I order prototypes.

What I’d like you to do
• Inspect and correct the 3.3 V regulation network, decoupling strategy, and ground return paths.
• Reroute any traces that compromise signal integrity or violate clearances on the current 2-layer stack-up.
• Tidy up silkscreen, keep-outs, and mounting details so the board snaps straight into a mikroBUS header without surprises.

Deliverables
• Updated KiCad project (schematic + PCB) with no ERC/DRC warnings.
• Production-ready Gerber, drill, and position files.
• Refreshed BOM if you swap or add any parts.

Timeline
I’d like the final files back in 3–5 days so I can send them straight to fabrication.

If you have sample screenshots or links to previous STM32 or similarly dense boards you finished, share a couple; I’ll pick quickly once I see a style that matches mine.
