+## Kit Contents (v1)
+
+1. Pre-flashed ESP32-S3 + SX1262 main board
+2. BME680 sensor module
+3. SPS30 sensor module with cable
+4. Wind sensor (anemometer + wind vane) with mounting hardware
+5. Solar panel (10W) with cable
+6. LiFePO4 battery (32700 cell in holder)

+
+## Certification Strategy
+
+- Obtain modular certification for the radio module where possible
+- Perform EMC and RF exposure testing for the complete assembled unit
+- Target markets: USA (FCC Part 15), EU (CE/RED), Canada (ISED)
+- Maintain technical construction files (TCF) for EU compliance
+
+## Assembly Difficulty
+
+Target: **Intermediate hobbyist** (can solder through-hole, crimp connectors, follow wiring diagrams). Estimated assembly time: 3-4 hours.
+
+Future v2 may offer a **pre-assembled** option for non-technical users.
