I got my hands on a few Tower Pro SG90 9G servos but cannot find their schematics or datasheet anywhere (besides that link).
I have the following concerns:
- Looks like they're rated for 4.8V, but will they tolerate a 5V supply?
- How do I determine the current they require, in amps, mA, etc.?
- There's 3 wires: brown, red & yellow-orange, what do each of these guys do?
- If I had to guess I'd say that red is power, another one is direction, and another one is the position to rotate to
