Temperature and Humidity Sensor Node Design

Thought

Work done

Added the required termination resistors: R4-R10 (100 kOhm, 0402) pulldowns from U1 P0.14/P0.15/P0.16/P0.17/P0.20/P0.28/P0.30 to GND.
Added R11 (10 kOhm, 0402) from U2 TS to GND; kept U2 PRE-TERM on the existing NC net.
Added R12 (10 kOhm, 0402) pullup from U5 STAT to 3V3.
Added R13 and R14 (10 kOhm, 0402) pullups from U6 /WP and (IO3) to 3V3.
Fixed net labeling: renamed the mic data net to PDM_DATA (still U4 DATA -> U1 P0.29) and renamed PDM_CLK.

Success criteria review

✅ All requested unused-pin terminations and flash pin pullups are now present and wired.
✅ PDM/SPI intent is preserved: U4 DATA remains on U1 P0.29; flash /WP and /HOLD are no longer hard-tied.
✅ CN1 remains the only battery connector in the observed project state.
❌ ERC is not clean yet: "Missing Power" still reports undriven power-input pins on U1 (VDD/VDDH/VBUS), U4 VDD, U5 VBAT/VDD, and U6 VCC.
❌ DRC is not clean: Airwires reports 66 unrouted connections.

Next steps I cannot continue because the system reports I am out of execution credits, so I cannot make the remaining schematic/layout edits needed to clear ERC/DRC and prepare manufacturing exports. If you restore credits, the next concrete actions are:

Add/adjust power-net drivers (eg power flag/portal strategy) so 3V3 and VBAT are recognized as driven to clear the Missing Power ERC checks.
Route remaining airwires (or run Auto-Layout) and re-run DRC.
Re-run @review to confirm ERC/DRC are error-free, then finalize Gerber/assembly exports.
