7.9.6 Time-of-Flight and gesture‑detection sensor (VL53L5)
VL53L5 is a state‑of‑the‑art, Time-of-Flight (ToF), laser-ranging sensor enhancing the ST FlightSense product
family.
The communication interface with STM32U585AII6Q is I
2
C. A shutdown control and interruption input is also
provided on STM32U585AII6Q. The I
2
C address is provided in Table 15. The I/O interface is described in
Table 20.
Caution: The laser output power must not be increased by any means and optics must not be used to focus the laser
beam. Use of controls or adjustments or performance of procedures other than those specified herein might
result in hazardous radiation exposure. Refer to the VL53L5 datasheet for more details.
