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 | C1 | passive | Internal reference (balance) capacitor interface. Connect a 1-10 nF NPO capacitor to GND (4.7 nF recommended). Should be placed close to the IC. |+| 2 | CSEL | passive | Sensitivity-adjust capacitor interface. Connect a 0-100 pF NPO capacitor to GND; smaller value gives higher sensitivity. Should be placed close to the IC. |+| 3 | KEY1 | input | Capacitive touch sensing input for channel 1. Connect to touch pad (typically 3mm-30mm square) through a ~1 kΩ series resistor. |+| 4 | KEY2 | input | Capacitive touch sensing input for channel 2. Connect to touch pad through a ~1 kΩ series resistor. |+| 5 | KEY3 | input | Capacitive touch sensing input for channel 3. Connect to touch pad through a ~1 kΩ series resistor. |+| 6 | OUT3 | output | Open-drain output for KEY3. Pulls low when KEY3 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ). |+| 7 | OUT2 | output | Open-drain output for KEY2. Pulls low when KEY2 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ). |+| 8 | OUT1 | output | Open-drain output for KEY1. Pulls low when KEY1 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ). |+| 9 | VDD | power_in | Positive supply input, 2.5 V to 5.5 V (absolute max 6.0 V). Typical current 394 µA at 3.0 V / 666 µA at 5.0 V; sleep current 7 µA / 11 µA. Datasheet recommends a 20 Ω series resistor from the supply rail and a 100 nF decoupling capacitor to GND. |+| 10 | GND | power_in | Ground (supply return). 0 V reference for all pins. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Sam wing AI03C ssop10 |+| Package | SSOP-10-150mil |+| Category | Sensor |+| Pins | 10 |++## CAD (KiCad official)++- Symbol: `AI03C ssop10`+- Footprint: `Package_SO:SSOP-10_3.9x4.9mm_P1.00mm`+- 3D model: SSOP-10-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Sam wing AI03C ssop10 datasheet](docs/ai03c-ssop10-datasheet.pdf) (None pp, sha256 `7aa77573448dbd92`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
