Features:
-
The VL53L0X is a time-of-flight ranging
system integrated into a compact module. This board is a carrier for the
VL53L0X, so we recommend careful reading of VL53L0X datasheet before using this product.
-
The VL53L0 uses flight sense technology to
precisely measure how long it takes for emitted pulses of infrared laser light
to the nearest object and be reflected back to a detector, so it can be
considered a tiny, self-contained lidar system.
-
This time-of-flight (TOF)
measurement enables it to accurately determine the absolute distance to a
target without the object's reflectance greatly influencing the measurement.
-
The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but
its effective range and accuracy (noise) heavily on ambient conditions
and target characteristics like reflectance and size, as well as the sensor
configuration. (The sensor's accuracy is specified to range from ±3% at best to
over ±10% in less optimal conditions.)
-
Ranging measurements are available through
the sensor's I2C (TWI) interface,
which is also used to configure sensor settings, and the sensor provides two
additional pins: a shutdown input and an interrupt
output.
-
The VL53L0X is a great IC, but its small,
leadless, LGA package makes it difficult for the typical student or hobbyist to
use.
-
It also operates at a recommended voltage of 2.8 V, which can make
interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our
breakout board addresses these issues, making it easier to get started using
the sensor, while keeping the overall size as small as possible.
PIN Description:
VDD Regulated 2.8 V output. Almost 150 mA is available to power external
components. (If you want to bypass the internal regulator, you can instead use
this pin as a 2.8 V input with VIN disconnected.)
VIN This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA
level shifters pull the I2C lines
high to this level.
GND The ground (0 V) connection for your power supply. Your I2C control source must also share a common ground
with this board.
SDA Level-shifted I2C data
line: HIGH is VIN, LOW is 0 V
SCL Level-shifted I2C clock
line: HIGH is VIN, LOW is 0 V
XSHUT 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.
