情境
User needs a practical Spirit Pi metal detector circuit diagram for an ESP32-S3-N16R8 build, including battery charging, power rails, search coil driver, and audio output.
這張圖裡有什麼
看懂背後的決策。
01
Use netlist mode with SPICE-style component IDs and explicit labels for clarity.
02
Model the ESP32-S3 as a type=mcu IC with power, ground, DAC audio, PWM coil drive, and sense pins.
03
Add damping resistor across the search coil for stable pulse-induction pulses.
Reuse this diagram as a power, charging, and audio subsystem reference for ESP32-based metal detector builds that need a clean, renderable schematic.
