Dennis Field / dvk-mx8m-bsb - History

Assign placeholder footprints to WWAN antennae (identical to GNSS ones for now), add haptic motor schematic symbol and split up the connector and motor footprints, now ready to generate netlist and import it into Pcbew without errors

Add proper WWAN reset circuit using a MMBT2222A NPN BJT along with a 100nF cap and a TVS diode, make needed adjustements to the WWAN's SIM card circuit (UIM-CLK and UIM-RESET caps are NC & added 4.7k series resistor to SIM_DETECT_O#), assign the MMBT2222A footprint to KiCad's official SOT-23 footprint (identical to the spec sheet's recommended land pattern)

If necessary, the NC cap pads on UIM-CLK and UIM-RESET can be tested with various values during the first prototype debugging phase.

Make recommended changes after reviewer examined pages 13, 15-20

Add pull-up resistor to nCS pin of the NOR flash chip, make electrolytic caps tantalums again due to a the price difference not being significant

added library symbol for short internal coaxial cables (from u.FL connector of M.2/MiniPCIE Card to ceramic antenna).
This component is not appearing at the pcb. The library symbols serves only as a memory aid.
Supplier information can be linked to it and should appear then on the BoM.

Add mounting holes to the schematic and assign the associated M2 hole footprint, add fiducial marks to schematic and assign the associated 1mm diameter copper with 2mm diameter solder mask opening footprint, make various visual adjustments throughout the schematic

Make a few minor aesthetic adjustments to the schematic

Replace logic gate packages with cheaper options, change associated footprints to ones which match the cheaper alternatives

Update WWAN mPCIe sheet by organizing a few things and fixing the component properties order
