| 2 | A1 | input | Slave address setting input; must not be left open. |
| 3 | A2 | input | Slave address setting input; must not be left open. |
| 4 | GND | power_in | Reference voltage of all inputs and outputs, 0V. |
| 5 | SDA | bidirectional | Serial data input and serial data output. |
| 6 | SCL | input | Serial clock input. |
| 7 | WP | input | Write protect terminal. |
| 8 | VCC | power_in | Power source connection, 1.6V to 5.5V single supply operation. |

## CAD (KiCad official)

- Symbol: `BR24G04NUX-3TTR`
- Footprint: `Package_SON:SON-8-1EP_3x2mm_P0.5mm_EP1.4x1.6mm`
- 3D model: VSON-8-EP(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `br24g04nux-3ttr-etched.step` / `br24g04nux-3ttr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `br24g04nux-3ttr.step` / `br24g04nux-3ttr.glb` are the bare package body.
