Dennis Field / dvk-mx8m-bsb - History

Wired connection SOM<->Audio codec.
Placed USB Hub under the SOM.
Wired connection SD-card - Hub/SDIO-bridge.
(A few existing connection had to be moved or change layer)
Some details of SD-card (passives etc.) are not yet done.

Give more room between smart-card tracks on the bottom layer and the USB diff pair in order to reduce the potential for crosstalk

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

Placement and routing of audio circuit.
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
