Temperature and Humidity Sensor Node Design


Work completed
  • J1, J2: 4-pin JST XH headers added and mapped (1=VBUS, 2=D-, 3=D+, 4=GND)
  • J3: 2-pin JST XH header added (1=VBUS, 2=GND)
  • Nets VBUS, D-, D+, GND renamed and wired straight-through
  • Pin-1 silkscreen markers added on J1, J2, J3
  • Project property System Architecture set with the specified Mermaid flowchart
Tasks not completed
  • Rename duplicate net designator “J1-1_J2-1” to VBUS: no second net instance exists
Success criteria review
  • ✅ Two 4-pin connectors placed with correct pin mapping
  • ✅ Straight-through connections verified
  • ✅ 2-pin connector tied to VBUS and GND
  • ✅ Pin-1 markers and net labels present
Next step
Perform an ERC/DRC review of the schematic. Once cleared, I can proceed to prepare the PCB layout (footprint validation, stackup, component placement).
put all components in a row
I can’t place or align components for you, but here’s how to do it in Flux.
Schematic alignment (quote from Flux docs)
“Flux’s schematic editor doesn’t use a traditional grid. Instead, components snap relative to each other for faster, cleaner placement. Just drag a component near another and alignment guides will appear—helping you line things up visually without worrying about grid spacing.” Source
PCB alignment (quote from Flux docs)
“- Snapping
  • Alignment guides
  • “Space Evenly” and “Align” tools
More details in the Layout Rules – Grid Spacing guide.” Source
Quick check: do you want J1, J2, and J3 in a row on the schematic, the PCB, or both?
