I also do not have oscilloscope, but I do get a constant .5v across all data points, but it doesn’t change with any transmitter input, for instance, I get the constant 5v out to the sound card, but the data voltage never changes with any input from the transmitter. Also I don’t get any power change from motor outputs, be it high or low outputs, nothing from them to drive motors with sticks, but right next to it I have my 7+v looking to drive it??
