Safety
5.1
Electrostatic precaution
The user should exercise electrostatic precautions, including using ground straps when using the X-
NUCLEO-53L1A2 expansion board. Failure to prevent electrostatic discharge could damage the device.

Laser considerations
The VL53L1 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.
