5 top-level parts · 16 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | MEMS Accelerometer | 1× | Piezoelectric or capacitive acceleration sensor. |
| 2 | Diaphragm Disc | 1× | Stainless steel resonant membrane, 40 mm diameter. |
| 3 | Sensor Preamp | 1× | Trans-impedance amplifier for capacitive sensor. |
