5 Safety
5.1 Electrostatic
precaution
Figure 9. Electrostatic logo
The user should exercise electrostatic precautions, including using ground straps when
using the X-NUCLEO-53L1A1 expansion board. Failure to prevent electrostatic discharge
could damage the device.
5.2 Laser
considerations
The VL53L1X contains a laser emitter and corresponding drive circuitry. The laser output is
designed to remain within Class 1 laser safety limits under all reasonably foreseeable
conditions including single faults, in compliance with the IEC 60825-1:2014 (third edition).
The laser output remains within Class 1 limits as long as STMicroelectronic’s recommended
device settings are used and the operating conditions specified in the datasheet are
respected. The laser output power must not be increased by any means and no optics
should be used with the intention of focusing the laser beam.
