Place and route the BOOT_CFG* signals, correct a signal labelling mistake causing SAI1_RXD0 (BOOT_CFG00) to be connected to SAI1_TXD0 (BOOT_CFG08)

BOOT_MODE* still needs to be placed & routed, need to find a good location for the SMD slide switches.

Place and route the WiFi+BT antennae circuits, reduce the radius of the PCB corners in order to make more room for the antennae

The top-right mounting hole is currently placed in an ~odd~ position in order to avoid the (AE1801) antenna's clearance area, a thin 0.475mm wide strip runs from the two ground planes to this mounting hole (between the two antennas' occupied area).

Add WiFi+BT antenna footprint, add pi matching circuit to the WiFi+BT antennas' feedlines, increment the capacitor part numbers on page 18 after adding the new (NC) feedline caps and make the respective changes to the reference designators in the BoM

Connections to speaker, mic, HKS and SOM not finalized because they depend on general placing.

Move and route the bypass caps and ferrite bead filter circuit for the GNSS's VCC & VCC_IO power inputs (coming from 3V3_P)

Connect the mPCIe mounting holes to ground, use common dimensions for the mPCIe mounting holes, update THT vs SMD definitions for various footprints, re-update all footprints in the layout

Place and route the GNSS antenna and its feedline, re-calculate the coplanar waveguide to 50Ohms using EmCraft's baseboard parameters (include new calculations), make the M.2 mounting hole connect to GND and use the recommended size for the hole's dimensions

(Small) change in library symbol of RJ45-mag-jack (inner circuit now machtches the picked mag-jack type).
Further routing and placing of ethernet group.

Next thing to add is the 5V_SOM rail and effectively the SoM board will be able to receive power via either a USB supply and/or a battery with nothing else added (basic operation functionality then implemented).

Add the speaker's 3D model, expand the speaker footprint's milled hole size and rotate its pads in order to closely conform to the 3D model

Deleted or repaired some errors introduced (by me) as kicad beginner (improper use of diff pairs, parts being off grid etc).

Place and route the rest of the battery sheet circuit, place and route the 10k (non-NC) resistors near the TCPC, route the EN_SRC and EN_SNK lines

TCPC still needs to be completed

Detected and corrected numbering error with MagJack J1701.
Eventually error with missing VCC of Pin 1 of J1707 (to be checked).

Route the USB diff pairs from the TVS protection + EMI filter IC circuit to the SoM, place and route the USB1_VBUS comparator circuit

Add new built-in mic's frequency response curve to the schematic and re-simulate the HP_DET pin circuit with the protection diode's SPICE model included

Swapped positions of M.2 and miniPCIE cards, as this results in less signal crossings under the SOM.
Moved some forgotten parts back to their respective groups.

Replace the CMC-6022-37T microphoen with the CMC-2242PBL-A THT one since the old one cannot be surface mounted/reflowed, add the microphone's 3D model

The microphone's pin position/order is agrees with the manufacturer's "measurement circuit" from the datasheet such that the right (facing the top of the mic) terminal/pin is its GND (-).

Update all of the 3D model paths to the new directory name structure, use the correct camera mating connector part number AXT530124 instead of AXT630124 which is the one found on the camera, add the camera connector's 3D model

Moved component groups closer to the center
Unrouted net lines are now shorter in general (density is unfortunately higher)
