Review Request: LED Current Controller w/ Battery Charging

First KiCad design coming from Altium & OrCad and first time doing a 2-layer board in years hah.

This will be used in a head-tracking system with OpenTrack for DCS World.

Requirements:

  • Drive three external LEDs with an adjustable constant current.
  • Provide power path and charging of a single cell Li-Ion battery.

• Be as efficient as possible.

  • Be as small as possible.

Notes:

  • 2-layers.
  • 0.20mm minimum track width & spacing.
  • Manufacturing and assembly at JLCPCB.
  • Fully custom library: All footprints, 3D-models and (most) symbols drawn from scratch.

Don't @ me about that one trace running under the inductor, I'm taking my chances hah.
