Ultrasonic U098 Sensor Datasheet

  • Is there a datasheet for the U098 sensor chip? The website list RCWL-9600 as the chip. However, there is no schematic and no datasheet for this chip that I can find. There is some example code that show banging in some magic numbers via I2C and getting other magic numbers back as the response. However, that does not really help me in using it correctly.
    Seems that at least there should be a list of available registers within the chip and their uses.
