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.

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

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

For better BoM generation, added placeholders for SOM, disṕlay, camera, WWAN card and wifi/BT card.
Datasheet links and supplier information can be stored in these new library symbols.

Add FDV301N footprint based on the manufacturer's given recommended land pattern, use lower ESR 220uF tantalum capacitors in place of previously selected ones, re-export the BoM

Double checked FET footprints to make sure those assigned to the official SOT-23 footprint are correct.

Add BLM18PG121SN1D chip ferrite beads to the GNSS, proximity+ambient light sensor, and IMU +3.3V power pins

Add MIC2876 5V boost converter's footprint, assign it, assign it the DFN-8 3D model
