## Description
|
||
|
||
**ToF** that employs time-of-flight techniques to resolve distance between the emit point and the reach point of a subject, measuring the round trip time of an artificial light signal provided by a laser.
|
||
|
||
This unit integrated a distance measuring sensor VL53L0x providing accurate distance measurement whatever the target reflectance, unlike conventional technologies. It can measure absolute distances up to 2m in less than 30ms.
|
||
|
||
This unit communicates with M5Core via I2C(0x29).
|
||
|
||
- In this case, make sure you use the 3.3V on SDA and SCL, M5Core GROVE provide 3.3V to data pins, 5V to power pin. only 3.3v allowed on VL53L0x.
|
||
|
||
## Product Features

||
|
||
- High precision
|
||
