7.6 User LEDs
5 LEDs are used as an output to indicate to the user the functioning of the module. Red LED glows constantly
indicating adequate power supply is available to the board. Four Green LED blinks continuously to indicate the
functioning of 4 DC Motors respectively.
7.7 Time of flight ranging sensor VL53L5CX
The VL53L5CX is a state of the art, Time-of-Flight (ToF), multizone ranging sensor enhancing the ST FlightSense
product family. Housed in a miniature reflowable package, it integrates a SPAD array, physical infrared filters, and
diffractive optical elements (DOE) to achieve the best ranging performance in various ambient lighting conditions
with a range of cover glass materials.
The use of a DOE above the vertical-cavity surface-emitting laser (VCSEL) allows a square FoV to be projected
onto the scene. The reflection of this light is focused by the receiver lens onto a SPAD array.Unlike conventional
IR sensors, the VL53L5CX uses ST's latest generation, direct ToF technology, which allows absolute distance
measurement whatever the target color and reflectance. It provides accurate ranging up to 400 cm and can work
at fast speeds (60 Hz), which makes it the fastest, multizone, miniature ToF sensor on the market.
Multizone distance measurements are possible up to 8x8 zones with a wide 65° diagonal FoV, which can be
reduced by software. Thanks to ST histogram patented algorithms, the VL53L5CX is able to detect different
objects within the FoV. The histogram also provides immunity to cover glass crosstalk beyond 60 cm.
