Confused... I have four 4-in-1 Orientation Sensor that match, exactly, the PCB depicted in the DYI picture marked "coming soon". I don't find this sensor in the list of my builder. There is the Gyro, the Accelerometer, and the 9150, and the 6050 but mine isn't there. I find plenty of articles about these things failing, and I read the article about how to convert the voltage returned and the sensitivity issues while performing the calculations. I actually understand all of that but in videos about the sensor, apparently, we don't need to do the calc's because the VB4 does it for us. I would need the specifications data to use this sensor on a Stamp but here, I don't. What I need to know is which sensor do I select for this unit if it isn't here yet. Since I have four of them, I'm kind of interested in how I INIT it. Use the 9150? That would be fine but is that why others fail? None of the PCB's in the PROJECT/ADD actually match these that I have and I can't find any other data other than coming-soon.
