Leo generated the vendor part with easyeda2kicad (C5120257) -> Drogheda-v6.kicad_sym / .pretty / .3dshapes, now registered in sym-lib-table and fp-lib-table. CROSS-CHECK: the EasyEDA/LCSC symbol independently CONFIRMS the datasheet transcription - pads 1-54 match the u-blox pin assignment function for function, and the 21 Reserved pads are identical. Pads 55-102 are 48 extra GND pads (the ground array under the module), which our symbol was missing; T3a2 adds them stacked on the pin-1 coordinate so one GND label serves all. Symbol is now 102/102 pins, footprint = Drogheda-v6:LCC-LGA-102_L22.0-W17.0_FM660. Block N as wired (verified by rebuilding connectivity from label-on-pin geometry): GNSS_TX U16.16 + U18.43 GNSS_RX U16.17 + U18.42 DOUT_4G U18.26 (RXD2, RTCM in - modem end lands in T4) USART1_RX U16.43 + Rdfu1.1 + U18.27 (TXD2 uplink; K1.1 also on this net per the PCB) GNSS_RESET_N U16.53 (PC12) + U18.49 + R105 10k pull-up to 3V3_GNSS GNSS_TIMEPULSE U16.23 (PA7) + U18.53 GNSS_ANT_DETECT U16.9 (PC1) + U18.4 GNSS_ANT_SHORT_N U16.10 (PC2) + U18.6 GNSS_RTK_STAT U16.11 (PC3) + U18.20 <- hardware answer to are-corrections-being-used 3V3_GNSS = U21.5 + U18.33/34 + C120-C124 + R105; U21 fed from SW_5V (stays MCU-gated) V_BCKP = U18.36 on the UNGATED 3V3 so ephemeris survives a power-cycle 33 no-connects: the 21 reserved pads plus V_USB, USB_DM/DP, ANT_OFF, SDA, SCL, TX_READY, D_SEL (open = UART mode), SAFEBOOT_N, EXTINT, GEOFENCE_STAT and the LDO NC/NR pin. T3c fixes two coordinates the generators emitted as 3.552713679e-15 (i.e. zero); KiCad is not guaranteed to accept exponent notation. See the script header for the lesson: a first attempt used a bare numeric regex over the whole file and corrupted 264 UUIDs, because segments such as 895e-4153 parse as scientific notation. Reverted from backup and redone scoped to (at ...) forms only, with a UUID-integrity guard. Verified 2298 UUIDs, 0 malformed, 0 exponent coordinates. STILL OPEN: the PCB has no U18/U21/passive footprints yet - that is a KiCad Update-PCB-from-Schematic. And confirm the -04B datasheet pin assignment on paper.
