This pull request introduces the initial PCB outline and layout groundwork for the LinHT hardware project.

Summary of Changes

  • Added mechanical PCB outline with defined board shape and size
  • Placed USB-C, 3.5 mm jack, and mounting holes according to expected enclosure constraints
  • Positioned SoM, the final placement has to be reviewed
  • Placed components for both step-down 3.3 and 5 V converters.
  • Updated board origin and grid for consistent placement and alignment
  • Changed footprint of the MCM-iMX93 SoM

Notes

  • This is an initial layout pass -- placement is not final and subject to change as the schematic evolves
  • No copper routing yet -- this PR is layout framework only
  • Mounting hole locations follow estimated enclosure dimensions

Excellent! One comment - SoM pads, including those labeled G[1-28], should not be covered with solder paste, otherwise it will be difficult to solder it without a hot plate.
