Session ended.
Work completed:
  • Updated project description and added system architecture diagram.
  • Placed core parts: ESP32-C3FH4 (U1), NAU7802SGI (U2), NCP176BMX330TCG (U4), RH100-40MHz crystal (Y1), 2450AT18B100E antenna (ANT1), MSD-4-A microSD connector (J1), 694101308002 barrel jack (J2), generic passives (C1–C4, L1), and ground.
  • Established basic 5 V and GND nets and connected decoupling and power pins.
Work not done (requires user action):
  • TPS62130ARGTR buck converter and associated inductor/Cout
  • USB-C receptacle and CC resistor network for power-only USB-C
  • 0532610471 load-cell connector and front-end filtering network
  • RF matching LC network and keep-out zone implementation
  • Rail-by-rail power-budget documentation and regulator sizing
  • I²C pull-up resistors
Success criteria status:
  • Core components integrated: Partially met.
  • Power subsystem design: Not met (buck converter, USB-C missing).
  • RF network: Not implemented.
  • Load-cell interface: Connector and filters missing.
  • Full documentation: Pending.
Next steps: add the missing power converter, connectors, RF matching components, pull-ups, and complete documentation for production readiness.

  • Generic Capacitor
    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available. Standard capacitor values: 1.0pF 10pF 100pF 1000pF 0.01uF 0.1uF 1.0uF 10uF 100uF 1000uF 10,000uF 1.1pF 11pF 110pF 1100pF 1.2pF 12pF 120pF 1200pF 1.3pF 13pF 130pF 1300pF 1.5pF 15pF 150pF 1500pF 0.015uF 0.15uF 1.5uF 15uF 150uF 1500uF 1.6pF 16pF 160pF 1600pF 1.8pF 18pF 180pF 1800pF 2.0pF 20pF 200pF 2000pF 2.2pF 22pF 20pF 2200pF 0.022uF 0.22uF 2.2uF 22uF 220uF 2200uF 2.4pF 24pF 240pF 2400pF 2.7pF 27pF 270pF 2700pF 3.0pF 30pF 300pF 3000pF 3.3pF 33pF 330pF 3300pF 0.033uF 0.33uF 3.3uF 33uF 330uF 3300uF 3.6pF 36pF 360pF 3600pF 3.9pF 39pF 390pF 3900pF 4.3pF 43pF 430pF 4300pF 4.7pF 47pF 470pF 4700pF 0.047uF 0.47uF 4.7uF 47uF 470uF 4700uF 5.1pF 51pF 510pF 5100pF 5.6pF 56pF 560pF 5600pF 6.2pF 62pF 620pF 6200pF 6.8pF 68pF 680pF 6800pF 0.068uF 0.68uF 6.8uF 68uF 680uF 6800uF 7.5pF 75pF 750pF 7500pF 8.2pF 82pF 820pF 8200pF 9.1pF 91pF 910pF 9100pF #generics #CommonPartsLibrary
