- New carrier/GPS_PPS.kicad_sch via tools/build_gps.py: J_GPS 5-pin (PPS + UART2 NMEA + 3V3_AUX + GND) per Pinout_BOM section 6 - PPS chain: GPS_PPS_RAW -> PESD3V3L1BA TVS -> 74LVC1G17 Schmitt (+3V3_AUX) -> PPS_CLEAN -> 33R series -> SYNC_OUT (CM5 pin 18 + J2.6), plus J_PPS1 (UWB) / J_PPS2 (scope) 2-pin taps; board is PPS sink only - NMEA on UART2 (GPIO4/GPIO5) per correction C2; debug console keeps UART0 - Converted SYNC_OUT/GPIO4/GPIO5 local labels on CM5_GPIO to global (names unchanged) to reach the new sheet; root sheet-symbol needs no pins - J_GPS pins 1/2 typed output (GPS drives PPS/TX) for driver-aware checks - Verify: ERC 133->133 zero new; analyzer +73/-0 zero regressions; netlist confirms all cross-sheet nets; SPICE 24 pass / 2 benign warn / 0 fail Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
