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.

// Howdy 👋.

// This is where you can create powerful part automations like resistors that tell you when too much current is flowing through them
// You can also create your own flexible parts, like generics (https://docs.flux.ai/Introduction/generic-parts)
