Make use MIC5365's SC-70-5 package instead of the SOT-23-5 package since it is a lower cost and is more available, assign it the official SC-70-5 3D model

Used Microchip's "Package Specification" document which on page 41 shows the recommended land pattern for their SC-70-5 packages (nominal pad dimensions are given but spacing is shown as min/max, used these values +/- 0.05mm for headroom).

The MIC5365-2.8YD5's recommended land pattern in the datasheet has inconsistent dimensions, so reasonable values are used based on the given TSOT-23 package's dimensions and KiCad's official SOT-23-5 footprint.

Create and assign RT8070 3.3V buck converter's footprint, import and assign its 3D model from the official KiCad repo

Re-export the BoM after bring the WLAN+BT M.2 sheet to page 18 and redoing the reference designator numbers.

Add the BQ25896 charge controller's missing pins which may make the schematic a bit ambiguous, reduce the value of the VBAT_REG LED's current limiting resistor to 1k in order to make it a bit brighter

This commit is thanks to our design reviewer's feedback.

Move the ground connection on the USB-C receptacle from the shield pin to the GND pins (shield is still connected to GND via the 0 ohm resistor), make the cap between the receptacle's GND and shield NC

This commit is thanks to the feedback from our design reviewer

Update Bill-of-Materials format and include missing SEC1110 datasheet link, fixed lingering component properties typos

Add AC coupling caps to the HDMI_AUXP/N diff pair which were mistakenly left out, fix a couple typos/errors that were made when transitioning to the new top-leve sheet, make the M.2s' I2C RX TX hierarchical signals consistent and clearer

Hopefully all lingering errors have been caught, this will likely be the schematic commit that gets reviewed (fingers crossed).

Assign TLV3201AIDBVR footprint based on the SOT-23-5 official footprint using the given solder mask clearance and pad clearance parameters, assign the QFN48 3D model to the ETH PHY footprint, make some minor adjustments to the front sheet's layout

Create AP22814 footprint and assign it to the respective symbols, use DFN-6-1EP_2x2mm_Pitch0.65mm 3D module for AP22814

Reorder USB-C's diff pairs based on layout simplicity as done on EmCraft's Rev 2 baseboard (requires Lane Polarity Inversion), add 2 and 3-channel differential filter & TVS IC footprints (used with USB-C and HDMI), import USB-C receptacle 3D model

Used a scaled version BGA-256_16x16_17.0x17.0mm_Pitch1.0mm 3D model for the filter&TVS diff pair chips, the perimeter balls are not very noticable at this shrunken scale and can be replaced later on (placeholder).

Move haptic motor connector footprint position such that 0,0 is between the through hole, this should make it so that its placement coordinates is closer to its center of mass

Remove emcr_mx8m.* files as they're no longer used, rename Purism_landscape.kicad_wks file to purism_landscape.kicad_wks (prefer all lower case letter for ease of use)

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

Reorganize the top-level sheet to make more room and allow most wires to be straight connections to their respective locations

Pin assignments still need to be double checked against the current one in the master branch.

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!

Create footprint for cap touch FPC connector and assign it, add cap touch FPC connector 3D model, assign M.2 Key E socket footprint, assign JTAG header footprint (will be unpopulated)

M.2 footprints will need mounting holes added to them for the modules to be brought close to the baseboard, this may pose a problem with the display mounted on the back and might need to be done a different way (needs evaluation). Cap touch and DSI connectors need to be carefully placed in the layout to make sure they are positioned correctly with respect to the display's FPCs and the outline of the display itself (need dimensions ASAP). JTAG header can be placed on the back of the board with the header unpopulated, will be hidden as it's only intended for intense last resort debugging option.

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

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

new library with symbol of Emcraft-SOM (for later use)

egarding the DPDT switches' & logic gates' pins being interchangeable

Used right-angled JST 2.5mm connector scaled in half as the motor connector footprint & 3D model, included 1cm distance from haptic motor placement from the edge of the connector (shown on silkscreen).

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

Some footprints are slightly edited versions of their KiCad official library equivalents, using the existing 3D models. DMG2301L's SOT-23 footprint is identical to the official one in the KiCad library.

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
