 Early data, what is this? Hey, I'm just doing a quick demo for a new product. This is the RCWL 1601. This is an ultrasonic sonar distance sensor. What's interesting about this is this one is in I squared C mode. So it does have a mode where you can query it over I squared C. I've got some resistors here because I built in pull-ups. And then I've got it plotting out the distance. I can put my hand up and down to change the output. It does work. I will say one thing about this. It doesn't seem to like to share the I squared C bus, but there's some situations where you don't want to use like the pin trigger pulse style of ultrasonic sonar sensor. You don't want the UART style. Maybe you don't have a PWM input. You have I squared C. And as long as you're cool with just not having anything else on that same bus, like in this case, I've got this OLED on a different bus. It seems to work just fine.
