Pico42: Simple Hand-Solderable PCB in BM40/JJ40 Form-Factor, rev 2023.2

A minor improvement over Pico42 rev2023.1.

Improvements

• Development Board cover plate: add mounting holes so a cover plate can be mounted to cover the development board area.
  • Using a cover over the development board is not necessary.
• Adding an extra mounting hole, for sandwich- or 3DP-cases.
• Smaller, symmetrical PCB outline.
  • Pico42 rev2023.1 retained the same PCB outline as BM40, which has extra margins around the switches to allow for the bigger Kailh hotswap socket footprints. Pico42 doesn't use hotswap sockets, so doesn't need this padding.

Build Guides and Release Assets

rev2023.2 is only a cosmetic update over rev2023.1; the build guide, etc. is the same.

Included below are:

• the Gerber files, for PCB fabrication.
• the SVG file for the devboard cover plate.

For other files (e.g. bottom plate, switch plate), see pico42 rev2023.1.

Source files for CAD cover plate can be found under cad/keyboard_plates.
