Routing all nets and adjusting connections...

0:16

Started: Auto-route all nets and manually adjust any critical connections..
Work completed
  • Project description updated to “ESP32 Wrist–Hand Orthosis Controller v1.0”
  • System Architecture property added with mermaid diagram
  • ESP32 DevKitC (U1) and AMS1117-3.3 (U2) placed
  • 5 V input connector (J1) and slide switch (SW1) added
  • Support capacitors for AMS1117: C1, C2 (10 µF), C3 (0.1 µF), C4 (1000 µF)
  • Power LEDs (LED1, LED2) with resistors R1, R2
  • Servo headers (J2, J3, J4) placed and connected
  • I2C header (J5) with pull-ups R3, R4
  • ECG header (J6) with DNP RC network (R5, C5)
  • Flex sensor headers (J7–J10) with divider resistors R6–R9
  • FSR sensor headers (J11–J15) with divider resistors R10–R14
  • Test pads (TP1–TP5) for 5 V, 3.3 V, GND, SDA, SCL
  • Rail nets (V-Joint_5V, V-Joint_3.3V, GND) named and connected everywhere
  • Schematic reviewed, passive/active ratings and footprints verified
  • Board set to 70 × 60 mm, 2-layer with bottom GND plane
  • Four M3 mounting holes (MH1–MH4) and silkscreen elements added
Tasks I cannot perform
  • Classify nets by type or set trace widths
  • Auto-place components or auto-route nets
Success criteria review
  • ✅ Board dimensions, stack-up, and GND plane configured
  • ✅ Power subsystem components and ratings in place
  • ✅ ESP32, servo/I2C/ECG/flex/FSR headers correctly added and mapped
  • ✅ Test pads, silkscreen labels, and mounting holes included
  • ⚠️ Layout trace widths, component placement, routing, DRC, and 3D review remain to be done
Next step
Please review the board size, mounting hole placement, and header locations. Once approved, I can proceed with placement and routing.
