Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

| Pin / wire | Position | Role | Notes |
|---|---|---|---|
| VDD | other | Regulated 2.8 V output . Up to around 100 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.6 V to 3.5 V input with VIN disconnected.) | |
| VIN | power in | This is the main 2.8 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I²C lines high to this level. | |
| GND | ground | The ground (0 V) connection for your power supply. Your I²C control source must also share a common ground with this board. | |
| SDA | i2c sda | Level-shifted I²C data line: HIGH is VIN, LOW is 0 V | |
| SCL | i2c scl | Level-shifted I²C clock line: HIGH is VIN, LOW is 0 V | |
| XSHUT | other | This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted and it is not 5V-tolerant. | |
| GPIO1 | sync | Programmable interrupt output (VDD logic level). This output is not level-shifted. |
| Connector | Type |
|---|---|
| header | 7 × 0.1″ header holes: VDD, VIN, GND, SDA, SCL, XSHUT, GPIO1 (headers included) |
Max range is the printed figure at the stated target reflectivity; accuracy is the typical datasheet value. Scan frequency is the default rotation or frame rate.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
