A1324LLHLX-T from Allegro MicroSystems LLC, in a SOT-23W. 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 | VCC | power_in | Supply voltage input. Operating range 4.5 V to 5.5 V (nominal 5 V). Bypass to GND with a 0.1 uF ceramic capacitor placed close to the pin. |
| 2 | VOUT | output | Analog ratiometric output voltage. Quiescent output is nominally VCC/2 with zero applied field; output changes with magnetic flux density at a nominal sensitivity of 5 mV/G. Drives loads with output impedance suitable for high-impedance sensing. |
| 3 | GND | power_in | Ground reference for supply and output. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 370 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
