+# Presence Sensor - PoE Variant
+
+Same sensors as the USB-C version, but powered and networked via Power over Ethernet (802.3af).
+
+## Key Differences from USB-C Version
+
+| Feature | USB-C Version | PoE Version |
+|---------|--------------|-------------|
+| Power | USB-C 5V | 802.3af PoE (48V → 5V) |
+| Network | WiFi only | Ethernet (wired) + WiFi fallback |
+| Connector | USB-C | RJ45 |
+| Extra chips | None | W5500 (Ethernet) + AG9905MT (PoE PD) |
+| Board size | 45x35mm | 50x40mm (RJ45 is bulky) |
+| Reliability | WiFi dependent | Wired, rock-solid |
+| Cost | ~$32 | ~$42 |
+
+## Why PoE is Better for Cameras
+
+- **No WiFi congestion** - camera streams are bandwidth-heavy
+- **Single cable** - power + data in one Ethernet run
+- **More reliable** - no WiFi dropouts
+- **Centralized power** - PoE switch manages all device power
+- **Remote reboot** - cycle PoE port to hard-reset device
+
+## New Components
+
+### W5500 Ethernet Controller
+- SPI interface to ESP32-S3
+- 10/100 Mbps Ethernet
+- Hardware TCP/IP stack (offloads ESP32)
+- QFP-48 package (7x7mm)
+- JLCPCB: C32843
+
+### RJ45 with Integrated Magnetics + PoE
+- HR911105A or equivalent
+- Includes PoE center-tap connections
+- Through-hole (adds height but very robust)
+
+### PoE PD Module - Silvertel Ag9905MT
+- IEEE 802.3af compliant (up to 13W)
+- 48V input → 5V/2A output
+- Tiny module: 16.5x14.5mm
+- Isolated, protected
+- Alternative: AG9905M-R or TI TPS2376 discrete
+
+### 25MHz Crystal Oscillator
+- Required by W5500
+- 3.2x2.5mm SMD package
+
+## GPIO Changes for PoE Variant
+
+| GPIO | USB-C Version | PoE Version |
+|------|--------------|-------------|
+| GPIO19 | USB D- | **Free** (no USB) |
+| GPIO20 | USB D+ | **Free** (no USB) |
+| GPIO33 | Free | **W5500 SPI MISO** |
+| GPIO34 | Free | **W5500 SPI MOSI** |
+| GPIO35 | Free | **W5500 SPI SCK** |
+| GPIO36 | Free | **W5500 SPI CS** |
+| GPIO37 | Free | **W5500 INT** |
+| GPIO42 | Free | **W5500 RST** |
+
+Camera, mmWave, PIR, I2C sensors - all unchanged.
+
+## Power Path
+
+```
+PoE Switch (48V)
+    │
+    ▼
+RJ45 Connector (center-taps)
+    │
+    ▼
+Ag9905MT PoE PD Module
+    │ (48V → 5V isolated)
+    ▼
+5V Rail ──→ LD2410C (direct)
+    │
+    ▼
+AMS1117-3.3
+    │
+    ▼
+3.3V Rail ──→ ESP32-S3, W5500, sensors, camera LDOs
+```
+
+## Power Budget (PoE)
+
+| Component | Voltage | Current |
+|-----------|---------|---------|
+| ESP32-S3 | 3.3V | 240mA |
+| W5500 | 3.3V | 132mA |
+| OV5640 | 2.8V+1.8V | 140mA |
+| LD2410C | 5V | 60mA |
+| AM312 + SHT41 + BH1750 | 3.3V | 3mA |
+| Ag9905MT overhead | - | ~50mA |
+| **Total from PoE** | 48V | **~180mA @ 48V (~8.6W)** |
+
+Well within 802.3af's 12.95W limit.
+
+## Board Layout Notes
+
+- RJ45 connector at bottom (cable exits down for wall mount)
+- Ag9905MT module near RJ45 (short high-voltage traces)
+- W5500 between RJ45 and ESP32 (short SPI traces)
+- Camera at top (unchanged)
+- mmWave on right (unchanged)
+- PIR on left (unchanged)
+- Sensors on left edge (unchanged)
+- Board slightly larger: 50x40mm to accommodate RJ45 jack height
