Pin Configuration

VL53L0X Laser Ranging Sensor Pinout Explanation
The VL53L0X is a high-accuracy laser ranging sensor designed for distance measurement applications. It features a low-power I2C interface and is suitable for use in a variety of IoT projects. Here's a breakdown of the sensor's pins and their functions:
Pinout Structure:
The VL53L0X sensor has 8 pins, which are arranged in a 2x4 configuration. The pins are labeled as follows:
Pin 1: VCC
Function: Power Supply (3.3V)
Description: This pin is used to power the sensor. A 3.3V power supply should be connected to this pin.
Pin 2: GND
Function: Ground
Description: This pin is the ground reference for the sensor. Connect it to the ground of your circuit.
Pin 3: SCL
Function: I2C Clock
Description: This pin is used for the I2C clock signal. It is an input pin that requires a pull-up resistor (typically 1 k to 10 k) to a 3.3V power supply.
Pin 4: SDA
Function: I2C Data
Description: This pin is used for the I2C data signal. It is a bi-directional pin that requires a pull-up resistor (typically 1 k to 10 k) to a 3.3V power supply.
Pin 5: XSHUT
Function: Shutdown
Description: This pin is used to shut down the sensor. When this pin is pulled low (connected to GND), the sensor enters a low-power state.
Pin 6: No Connection
Function: None
Description: This pin is not connected internally and should be left unconnected.
Pin 7: No Connection
Function: None
Description: This pin is not connected internally and should be left unconnected.
Pin 8: GPIO1
Function: General Purpose Input/Output
Description: This pin can be used as a general-purpose input or output. It is not used for I2C communication.
Connection Guidelines:
When connecting the VL53L0X sensor to your circuit, follow these guidelines:
Power the sensor using a 3.3V power supply (VCC pin).
Connect the ground of your circuit to the GND pin.
Connect the I2C clock signal (SCL pin) to the I2C clock line of your microcontroller, with a pull-up resistor (typically 1 k to 10 k) to a 3.3V power supply.
Connect the I2C data signal (SDA pin) to the I2C data line of your microcontroller, with a pull-up resistor (typically 1 k to 10 k) to a 3.3V power supply.
Leave the XSHUT pin unconnected if you want the sensor to operate continuously. If you want to shut down the sensor, connect this pin to GND.
Leave pins 6 and 7 unconnected, as they are not internally connected.
Use the GPIO1 pin as a general-purpose input or output, if necessary.
Remember to consult the sensor's datasheet and your microcontroller's documentation for specific connection and configuration requirements.
