Customer:
I’m looking for information about distance sensors. What are the specifications for the VL53L0X and VL53L1X? How do their measurement ranges compare?
I found a tutorial request for your ADC 3.3V 4-channel module but couldn’t find any documentation. Do you have any example code for using it?
Regarding the HX711 24-bit ADC with amplifier - what is the sensor precision when it’s loaded? What is the precision of the sensor itself?
I also need to know how to connect multiple I2C devices to Arduino. Are they connected in parallel to the outputs? Do you have any example code?

We have the VL53L1X which is very similar to the VL53L0X. VL53L1X measures up to 400cm, VL53L0X up to 200cm. Everything else is the same.
The VL53L0X modules from the two links you provided are identical, just different PCB form factor and manufacturer.
The ADC module from our website is no longer available and we don’t have a tutorial for it, so we won’t be developing one. We’re preparing a new breakout with ADS1115 for which we will have a tutorial.
The precision of an ADC for a scale depends on the load cell sensor. The ADC itself can achieve several decimal places of grams precision.
Multiple I2C devices are connected by joining their SDA and SCL lines together, plus of course the power supply. You need to combine the code from each sensor into one code so they work together.

mi imamo VL53L1X što je jako slično VL53L0X. VL53L0X mjeri do 400cm, VL53L0X do 200cm. Sve ostalo je isto. VL53L0X sa prva dva linka su isti, samo je drugi oblik pločice / proizvođač. ADC s linka na našim stranicama se više ne može nabaviti, nemam tutorijal, pa nećemo ga ni raditi. Pripremamo novi breakout s ADS1115 za kojega ćemo imati tutorijal. Preciznost ADC-a za vagu ovisi o senzoru mase. Sam ADC može ići i do nekoliko decimala grama. Više I2C uređaja se spajaju tako da im spojite zajedno SDA i SCL linije ta naravno napajanje. Svaki kod od svakog senzora morate spojiti u jedan kod kako bi radili zajedno.
