VL53L0X Current usage

by PikesPeakAdafruit on Tue Apr 23, 2019 10:50 pm

Hi,

I'm building a project that uses 9 VL53L0X boards. Three are on a single board that I made, and each of those has an AMS1117-50 1 amp voltage regulator.

It's controlled by a Raspberry Pi 3 B+, and if I keep all the '53's in shutdown mode, I can access any of the 9 over I2C. It works pretty well.

I've burned out (let out the magic smoke!) several of the AMS1117-50s, and I'm not sure why. They are good for only about 1 amp at 5 volts. Can you tell me how much current the VL53L0X uses, both when active and in shutdown mode?

Thanks for your help!

The V53L0X only uses about 20mA when the laser is active, and less than 10uA when idle. That shouldn't add enough load to kill a voltage regulator.

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.
