5 Safety
5.1 Electrostatic
precaution
Figure 9. Electrostatic logo
You should exercise electrostatic precautions, including using ground straps when using the
X-NUCLEO-53L0A1 expansion board. Failure to prevent electrostatic discharge could
damage the device.
5.2 Laser
considerations
The VL53L0X 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 IEC 60825-1:2014 (third edition). The
laser output will remain within Class 1 limits as long as the STMicroelectronics
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.
