q. on GY-VL53L0XV2 (breakout for ST VL53L0X ToF module)
(1/1)
TechieTX:
I've been looking at building a handful of monitors for our CPR manikins to get immediate feedback on the quality of compressions (depth of compression, full release, and BPM). We have Prestan Ultralite manikins, and the spring force feedback tower in the chest looks like the only decent place for sensing. Pouring over datasheets, most sensors flat won't work, or are too complicated to derive accurate depth (accelerometers).
The ST VL53L0X looks to be the winner, but the only boards I can find with decent mounting considerations are no-name clones sold as GY-VL53L0XV2. Looking at a couple of good res photos, I see what looks like a 3.3V Torex or Sunrom regulator on a board that should have a 2.8V LDO reg. ???
Asking the China sellers is a waste of time, and I don't want to wait a month to find out the boards are junk. Anyone here have one that can verify the SOT-23 part is actually putting out 2.8V, and not 3.3V as the 662K marking suggests?
If you're curious, here's the basic parts:
Not shown: ESP8266 D1 Mini, 1.8" OLED display, and a battery pack (TBD).
I like the GUI for the Laerdal CPRmeter 2, but at $700 a pop, they're out of their freaking minds when I can do the same with $15 worth of parts. Since the ESP has WiFi, I can monitor all 4 units from my phone while walking around and offering guidance & coaching during the practice session.
kathy:
I think SOT-23 part is suitable for OLED display module via the I2C port. the monochrome oled interface can be simple, spi or I2C interface are available.
