Smart Running Insole PCB Design
0:00
Started implementing a plan
## Goal
Create a manufacturable right-foot “master” insole PCB project in Flux EDA (ESP32-S3 + CD74HC4067 FSR mux + Li-ion charging + microSD + connectors), with a long insole form factor and zoning (toe/ball/arch/heel), ready for routing, DRC-clean, and export.
## What’s been completed
- **Project renamed** from placeholder to **`insole_master_right`**.
- **Schematic baseline exists** and was inspected at a high level (179 components, 63 nets). Major parts present: **U1 ESP32-S3-WROOM-1**, **U2 CD74HC4067M**, **U4 AP2112K-3.3TRG1**, **U5 TP4056**, **J1 USB‑C (CUI_UJC-HP-3-SMT-TR footprint)**, **J2 JST-PH 2-pin**, **J3 FFC2B28-16-G**, **J4 microSD (MEM2085-00-115-00-A)**.
- **PCB outline and global rules set**: rectangle **280mm × 90mm**, **cornerRadius=2mm**, **Standard 2 Layer** stackup; rules: **minTraceWidth=0.15mm**, **minKeepOut=0.15mm**, **minHoleSize=0.3mm**, **boardInsetMargin=0.5mm**.
- **Placement zoning started** via a coordinate-based placement pass and grouping into zones:
- `group-toe` (J1)
- `group-ball` (U2 + nearby passives)
- `group-arch` (U1, U4, J4 + caps)
- `group-heel` (U5, J2, J3 + passives)
- **Net-type annotation added** for routing priority (GND/power/analog/low-speed). Note: tool flagged **USB_CC1/USB_CC2 as “high-speed 90Ω”**, which is likely incorrect and needs correction.
- **Current DRC status**: **101 airwires**, **12 overlapping copper**, **89 floating copper**; missing footprints/invalid layer checks pass.
- **Auto-router attempt failed** due to router availability (`unavailable`), so no routing progress was made.
- **Stackup templates availability checked** (standard 1/2/4/6… and JLC/PCBWay 4-layer templates are available), but no stackup change was applied.
## Implementation plan (remaining work only)
1. **Resolve copper geometry errors in the PCB layout** by locating and removing/repairing the sources of **12 overlapping copper** and **89 floating copper** (likely stray pours/shapes). Re-run DRC until overlapping/floating copper errors are cleared.
2. **Verify and finalize placement** by inspecting the baked element positions/orientations for U1/U2/U4/U5/J1/J2/J3/J4 and adjusting placement rules as needed to meet edge clearances and zoning intent.
3. **Implement ESP32-S3 antenna keepout**: obtain the correct board-level element UID for U1 and apply a keepout rule/polygon that blocks copper (top/bottom) under and in front of the antenna region; ensure U1 is at a board edge with antenna facing outward.
4. **Correct net classification/constraints for USB-C CC pins**: set **USB_CC1/USB_CC2** to low/medium-speed (no 90Ω impedance constraint), and ensure CC resistors are treated as short, low-current traces per USB-C sink/UFP practice.
5. **Configure ground strategy for 2-layer**: enable a continuous **bottom-layer GND fill** (with thermal reliefs as appropriate), and maintain the antenna keepout void in the GND pour beneath the ESP32 antenna area.
6. **Complete routing** of all remaining connections (still **101 airwires**) using an available routing approach (manual routing by the human in Flux UI, or switching to a router that is available). Route in order: **VBUS_5V/BAT_PLUS**, **3V3**, **FSR_ADC (analog)**, then remaining digital lines.
7. **Re-run DRC/Electrical checks** after routing and fixes: confirm **0 airwires**, no copper overlap/floating copper, and no ERC power/undriven issues.
8. **BOM readiness pass**: assign real MPN/value/package properties for **Generic Resistor (R1,R2,R5–R8)** and **Generic Capacitor (C1–C13)** so the design is procurement-ready.
9. **Prepare manufacturing export**: once DRC-clean, generate Gerbers/drill and (if assembly) centroid files; add/verify fab notes for board thickness target (≤1.0mm) and edge-routing to the final insole silhouette DXF (if used).
