Pin & Connector Layout
| Pin | Voltage Level | Function |
|---|---|---|
| VCC | 3.3 V – 5.5 V | Provides power to the on-board regulator and sensor core. |
| GND | 0 V | Common reference for power and signals. |
| SDA | 1.8 V to VCC | Serial data line for I²C communications. |
| SCL | 1.8 V to VCC | Serial clock line for I²C communications. |
Note: The module also includes a Qwiic/STEMMA QT connector carrying the same four signals (VCC, GND, SDA, SCL) for effortless daisy-chaining.
