What is this tool?
Typical hobby servos interpret pulse width within a frame (often ~20 ms / 50 Hz). Many map roughly 1000–2000 µs across 0–180°, but endpoints vary by model — this tool lets you set the range and convert either direction.
How to use it
- Set angle range and pulse min/max (and frame period if needed).
- Enter angle to get pulse/duty, or enter pulse to get angle.
- Confirm against your servo datasheet before commanding hardware.
