Ambient Auto-Calibration
One-button calibration. Device listens to your environment and auto-tunes thresholds. No drone needed.
Adaptive Noise Gate
Continuously adjusts T0 gate based on ambient noise floor. Reduces false positives in changing environments.
Verify Detection
Play drone audio on your phone at ~3-5m to validate detection works.

Battery Consumption Test
Run field mode for a set duration, then auto-restore WiFi and generate a power report.
Duty cycle: 10% active. Saved to device (also used by Field Deploy). Lower = longer battery.
V4 boards (4.9x divider): 30+ min recommended for accurate results. Short tests (<10 min) may show unreliable data due to ADC resolution (~5mV/step).

🔌 Cable Test — Mic 1
Test each I2S wire by touching it to the LED test point.
When a pin is active, the LED should light up.
🔌 Cable Test — Mic 2
Mic 2 clocks are synchronized with Mic 1 via GPIO matrix (no Y-wiring needed). Each mic has its own pins.
SCK — shared with Mic 1 (GPIO5)
WS — shared with Mic 1 (GPIO6)
