Application schematic

Figure 3 shows the application schematic of the VL53L1X.

Note:

Capacitors on external supply AVDD should be placed as close as possible to the

AVDDVCSEL and AVSSVCSEL module pins.

Note:

External pull up resistor values can be found in I2C-bus specification. Pull ups are typically

fitted only once per bus, near the host. For suggested values see Table 3.

Note:

XSHUT pin must always be driven to avoid leakage current. A pull up is needed if the host

state is not known.

XSHUT is needed to use HW standby mode (no I2C communication).

Note:

XSHUT and GPIO1 pull up recommended values are 10 kOhms

Note:

GPIO1 to be left unconnected if not used

Table 3 show recommended values for the pull up and series resistors for an AVDD of 1.8 V

to 2.8 V in I2C Fast mode (up to 400 kHz).
