Work done
  • Updated project description to “Zero-Drain Automotive ESP32-C3 CAN Node with TJA1043T Power Management”
  • Defined system architecture with a Mermaid diagram and saved it to the System Architecture property
Remaining tasks
  • Add core components: ESP32-C3-MINI-1-N4, TJA1043T/118, MP2315SGJ-Z, AP2112K-3.3, NUP2105L, SS34, and JST-XH 4-pin connector
  • Add supporting passives: 31.6 kΩ & 6.34 kΩ feedback resistors, 4.7 µH inductor, 10 µF/22 µF/1 µF caps, 0.1 µF decoupling caps, 120 Ω resistor & 3-pad jumper
  • Connect all nets: power rails, regulator outputs, logic control pins, data interfaces, decoupling
  • Review schematic for completeness against functional goals
Success criteria None of the core success criteria have been met yet—no components or nets are placed or routed.
Next step I recommend proceeding with the “Key components” phase by placing and configuring all major ICs (step 3 of the implementation plan).
