Dennis Field / dvk-mx8m-bsb - History

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

Move and route the current limiting resistor for the charge controller circuit

Wired some of the bypass capacitors at the ethernet PHY.

Routing of signals between ethernet PHY and SOM, mainly on layer In2.Cu.

Changes in the rough placement:
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

Rotate the USB-C TCPC PHY 180 degrees after the SoM has been rotated

Rotated SOM by 180 degrees (mainly for shorter display connection)
Moved component groups closer to the center
Unrouted net lines are now shorter in general (density is unfortunately higher)
