Pinout & usage notes
Check the supported input voltage before wiring so the module matches your controller and power source. For analog readings, use a stable reference and keep wiring short when possible for cleaner signals. If you are using Gravity connectors, align the plug correctly and avoid forcing the cable into the wrong header.
