This post is just to document using a VL6180X Satellite module to measure distance to a range of 100mm (about 4 inches).
The VL6180X Satellites come in a little package from ST Micro. Inside are two identical VL6180X modules. Each module has a voltage regulator, a bunch of passive parts, and the VL6180X chip.
Here are a couple things to know about the chip:
- Communicates using i2c.
- Operates on 2.7V (hence the regulator).
- Has a range of 100mm (about 4 inches).
- Can output ambient light levels and distance at about 10Hz.
- There are ready made libraries available inside the Arduino IDE. Simply search for the libraries using the keyword “VL6180X”. Adafruit, among others, should pop right up. This post uses the library from Pololu that can be found here. Note, it is simpler to use the library manager inside the Arduino IDE to install this software, as compared to, installing using the provided link.
