is this pin out gnd vcc data from r1 -> s ?

1 VCC external 5V 2 GND External GND 3 DO small board digital output interface

will this work with 3.3 v? or 5 v only

works with both, but it's recommended to keep it around 3.3v

The tl1838 is pinned as stated 1vcc 5v 2 gnd 3 do, but this sensor gets very hot if used liked that, the correct way seems to be DO, vcc, gnd ?

The header pins are in a different order for some reason, confusing. Data Out is in the same position while VCC and GND are switched.
