Resolving Copper DRC Errors
Thought for 7 sec
I can’t cancel that server-side auto-layout job from the chat tools. You’ll need to discard it manually in the Flux UI job/auto-layout panel.
Once it is cleared, send:
rerun focused route
Then I’ll run exactly:
- one routing attempt
- one DRC count check
- stop immediately.
rerun focused route
Thought for 8 sec
I’ll run exactly one routing attempt, then one DRC count check, and stop.
Worked for 47 sec
Routing attempt failed: the same stuck
outOfCredit job is still active.Final DRC count check: 130 items remain.

BOM Update — RGB LED and Battery NTC Safety Add
Summary
This document records the latest BOM-impacting design changes:
- Replaced separate blue BLE/status LED and red charge LED with one addressable RGB LED.
- Added BQ25180 battery-temperature sensing using a 10 kΩ NTC thermistor and 10 kΩ VBAT pull-up on the TS/MR node.

Table
| Ref | MPN | Manufacturer | Description | Package / Footprint | Qty | Est. unit price qty 1 | Est. unit price qty 500 | Placement / assembly note |
|---|---|---|---|---|---|---|---|---|
| D1 | WS2812B-Mini | Worldsemi | Addressable RGB LED, 3535 package, single-wire data input; replaces separate BLE/status and charge LEDs | 3535 SMD | 1 | ~$0.07–$0.11 | TBD from assembly quote | Top board edge, visible through case window; verify pin-1/orientation marker and LED polarity/orientation in assembly drawing. |
| R1 | CRCW040233R0JNEDC | Vishay | 33 Ω 0402 series resistor for WS2812B DIN EMI/data damping | 0402 / 1005 metric | 1 | ~$0.002–$0.10 | TBD from assembly quote | Place close to nRF5340 GPIO source. |
| C50 | Generic 100 nF MLCC | TBD | Local bypass capacitor for WS2812B VDD | 0402 / 1005 metric | 1 | TBD | TBD | Place adjacent to D1 VDD/VSS. |
| RT1 | NCP15XH103F03RC or equivalent | Murata or equivalent | 10 kΩ NTC thermistor, B≈3950 K, battery temperature monitor for BQ25180 TS/MR | 0402 / 1005 metric | 1 | TBD — exact Flux-library part pending | TBD — exact Flux-library part pending | Safety-critical: mount in direct thermal contact with LiPo cell; keep away from charger IC, RGB LED, and regulator heat sources. Enables charge suspend outside safe LiPo charging range. |
| R2 | RC0402JR-0710KL | YAGEO | 10 kΩ 0402 pull-up from TS/MR node to VBAT for NTC divider | 0402 / 1005 metric | 1 | ~$0.0003–$0.10 | TBD from assembly quote | Place near BQ25180 TS/MR pin and RT1 routing. |

Table
| Ref | Previous part | Reason |
|---|---|---|
| D1 previous | 150060BS73220 blue LED | Replaced by WS2812B-Mini RGB LED. |
| D2 | SML-D14U2WT86C red LED | Replaced by WS2812B-Mini RGB LED; BQ25180 status now feeds MCU GPIO. |
| R1 previous | 1 kΩ LED resistor | Removed with discrete blue LED path. |
| R2 previous | 1 kΩ LED resistor | Removed with discrete charge LED path. |
Connectivity Notes
- WS2812B-Mini VDD → 3V3; VSS → GND; DIN driven from nRF5340 P0.13 through 33 Ω series resistor; DOUT is no-connect.
- BQ25180 ~INT/status → nRF5340 P0.14 GPIO input so firmware controls all LED states through D1.
- BQ25180 TS/MR node now includes push-button/debounce plus battery NTC divider: 10 kΩ pull-up to VBAT and 10 kΩ NTC to GND.
Open Accuracy Items
- Replace RT1 placeholder with exact Murata NCP15XH103F03RC library component once available, or import/create the exact MacroFab-approved part before release.
- Qty-500 pricing should be refreshed from distributor/MacroFab quote after final AVL is locked.
