Dennis Field / dvk-mx8m-bsb - History

Move more symbols, sheets, and pins around on the front sheet to make it even clearer, bring back the old hierarchical structure (again), bring back each sheet's title, add large text "titles" to each sheet reflecting what they are for

Still need to double check everything on the first page.

Small visual enhancements on top level page - e. g. at least one grid space around schematic blocks.
Double-labelled I2C busses to indicate clearly that they are point-to-multipoint connections and not just point to point.
Reduced drawing field and logo a bit in size (saves space).

Make all sheets except the top-level one identical to master, also checkout master's dvk-mx8m-bsb-cache.lib file

Add GNSS antenna footprint including correct 50Ohm feed line dimensions and keepout area, add u-blox MAX-8 3D model, rename all instances of MAX-M8* to MAX-8* due to part selection, antenna feed line calculatos included (coplanar waveguide)

Need to add placeholder footprints for the other four antennae which will be represented as simple rectangular areas where the antennae will occupy. After that, all that is left is to assign the various remaining IC footprints and finally import all footprints into PCBNew & begin layout!

Assign jumper header footprints and component properties, selected based on required current rating and minimized area occupied, assigned 1.5mm diameter test points

new structure of first page in the schematics
more direct connections instead of labels
interconnection of schematic blocks (e.g. USB hub) is made visible
format of page is now A3 instead of A2 -> better font quality when printed on small paper

added company logo and designers email addresses into drawing area
new library with symbol of Emcraft-SOM (for later use)

Add quartz crystal footprints, reassign BHC-18650-1P footprint & associated component properties, add BHC-18650-1P 3D model

Connect VCC of the USB1_VBUS comparitor (TLV3201AIDBVR) to 5V_SOM instead of 5V_P so that VBUS presence can be detected quickly enough for the USB Serial Downloader bootmode, connect the TVS diodes on the HDMI receptacle to the proper pins
