Project description updated and system architecture diagram defined
All core modules added (MCU, GNSS, LoRa, charger, LDO, USB-C, u.FL, JST-PH) and auxiliary headers/test points placed
Power subsystem wired: battery → charger → LDO → 3.3 V rail with decoupling capacitors
USB-C VBUS and CC resistors connected
MCU UART and SPI nets correctly routed to GNSS and LoRa modules
SWD and UART debug headers/test points wired
Status LEDs with series resistors connected
Schematic reviewed; no missing passives or nets
PCB outline enlarged, mounting holes added, and board auto-routed
DRC and ERC cleared (no issues)
Real MPNs assigned to all passive and active components
Tasks not performed
Configuring PCB stackup to Standard 2-layer and ground fills
Footprint verification for all components
Classifying nets by type and setting proper impedance/trace widths
Manual component placement refinement
Finalizing BOM and generating pick-and-place file
Exporting PDF schematic, Gerber/drill files, and other manufacturing outputs
Success criteria status
✅ Schematic completeness and rule-check compliance
⚠️ PCB layout exists but lacks controlled impedance routing and refined placement
❌ Manufacturing outputs (Gerbers, pick-and-place, PDF schematic) have not been generated
Recommended next step
Proceed with PCB preparation: configure the 2-layer stackup and ground pour, verify footprints, classify nets and set appropriate trace widths (especially for RF paths), then finalize the BOM and export the PDF schematic, Gerbers/drill files, and pick-and-place outputs.
