I needed to know 1. if it was a voltage regulator, and 2. how it was put together. So I did.... First off, yes, it is a step down regulator. It uses the KB33 voltage regulator which is a 3.3 volt 150mA regulator. That is perfect. Now, I needed to know what the other components were. There are 3 of them, 2 ceramic capacitors and one resistor. The larger capacitor is for the input and is a 3µf cap, and the smaller one is a 1µf cap. Simple. The resistor is a 562 smd resistor which is a 5.6kΩ resistor. Okay, we have the components (yes, that is all of them) now all we have to do is map out where they go. The signal wire is a straight passthough, nothing in the way. The ground is also a direct passthrough, but it connects to the ground side of the capacitors and the voltage regulator. The positive in connects to the in gate of the regulator and the out gate of the regulator goes to the positive pin of the satellite Rx. The positives and negatives, as stated, have the capacitors sitting on the rails for a little extra punch when it is needed. The part that is weirding me out is that 5.6kΩ resistor is sitting between the positive output rail (going to the satellite) and the signal wire of the satellite. I have no idea why there is a resistor there, but it's there. The signal wire from the gyro to the satellite is a straight through trace. This is interesting. But I now have enough information to make this drop down converter so that I can make another one of these for the other MB gyro that I have. Although by the time I order all of the parts, it will likely be more expensive and definitely larger than the OG lol. Very interesting though.</blockquote>
