Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT | output | Key sense value output. Behavior depends on MD pin: MD=floating → open-drain active-low (requires external pull-up); MD=VDD → push-pull active-high direct output; MD=GND → toggle/self-latch output starting low, inverting on each press. Isk = 10 mA @ VCC=5V, low-level output impedance ≈ 50 Ω, high-Z impedance ≈ 100 MΩ. |+| 2 | GND | power_in | Ground / negative supply reference (0 V). |+| 3 | KEY | input | Touch sense input pin. Connects to the touch pad (sense antenna) through a series resistor (RX ≈ 2 kΩ typical, range 0-5 kΩ). Minimum detectable capacitance change ≈ 0.2 pF. |+| 4 | MD | input | Output-mode select input. Three states: floating → OUT is active-low open-drain (needs external pull-up); tied to VDD → OUT is active-high push-pull direct output; tied to GND → OUT is toggle/self-latch mode starting low. |+| 5 | VDD | power_in | Positive supply input. Operating range 2.5 V to 6.5 V. Typical Idd = 1.6 mA @ 5.0 V, 0.8 mA @ 3.0 V. Decouple with 100 nF close to pin plus a 20 Ω series resistor from the rail as shown in the reference schematic. |+| 6 | C1 | passive | Internal reference source output. Requires a 4.7 nF capacitor to GND placed close to the pin. Do not load with anything else. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Sam wing |+| Package | SOT-23-6 |+| Category | Sensor |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `AI01K sot23-6`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Sam wing datasheet](docs/ai01k-sot23-6-datasheet.pdf) (8 pp, sha256 `2f962aec2e03de87`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
