      Place and route the JTAG circuit, place and route the BOOT_MODE slide switch circuit, place and route the user-LED circuit, place and route the top-level sheet passive components (I2C2 pull-ups, 5V_SOM, 3V3_OUT, & ENET_2V5 bypass caps, PWR_EN pull-down, USB2_VBUS voltage divider for SoC's comparator, etc), route the microphone to the analog audio switch IC, update the schematic, BoM, and footprints to reflect the MHF4 coax cable change (including them being 5cm long)
      
      Unrouted count is now 324. The power circuit and the display are what is now left to be placed on the board, a few nets currently on the board still need to be connected (~120). 3V3_SNVS and various other misc. power rails still need to be routed on the power plane (vias need to be placed near pads).
      
      JTAG header footprint is accessible from the display side (not underneath the display). User-LED is in a location as-close-as-possible to the bottom center of the board (somewhat near the microphone).
      
      Serpentine bends still need to be added to the CSI to match the intra-pair skew, still need to move the prox sensor to the top of the board!

      Now using GPIO5_IO03 (P4.03) to put the class-D op-amp in shutdown and conserve energy when muted, make C1716 near the ETH PHY's DVDDL pin 47 220nF instead of 10uF (EmCraft suggested that this should be 100nF but their's is 220nF, asked why), added a 10k pull-down to PAM2841's ENA pin, added a 100nF cap to the smart card's C1 VCC pin, added a 1uF cap to the haptic motor circuit's 3V3_P rail
      
      Still need to use I2C3 instead of I2C1 according to EmCraft's suggestions.

      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.
