Section: Phase 2: Technical Blueprint

5. HARDWARE_SCHEMATIC.md

Purpose: To define components, pin mappings, wiring diagram, and power requirements.

Act as a senior hardware engineer.
Using the PRD and System Architecture below, design the hardware schematic for this IoT hackathon project.

PRD: [PASTE PRD]
ARCHITECTURE: [PASTE SYSTEM_ARCHITECTURE]

Provide:
1. Bill of Materials (BOM) — All components with quantities
2. Microcontroller pin mapping (Which pin connects to what)
3. Wiring diagram (Text-based, showing connections)
4. Power distribution (Voltage, Current, Regulators)
5. Sensor connections (I2C, SPI, Analog, Digital)
6. Actuator connections (PWM, Digital, Relay)
7. Communication module connections (WiFi, Bluetooth, LoRa)
8. Grounding and noise considerations
9. Physical layout suggestions
10. A checklist for verifying hardware connections before powering on

Explain why each component is needed.
Keep the hardware simple enough for a beginner hackathon team to assemble and debug.
