Neutral sample
Stick drift and deadzone
Set the controller on a steady surface and do not touch either stick during the sample.
Ready for an 8-second sample.

8BitDo Controller Test
Test browser-visible input from 8BitDo controllers. Check buttons, sticks, triggers, and mapping across supported connection modes.
Local-only test
Connect with USB, Bluetooth, or a supported wireless adapter. Then press any controller button so your browser can expose it. Your readings are processed on this device.

Range and circularity
Rotate each stick slowly around the outer edge, then sweep the center in several directions.
Move the sticks to begin range tracking.

Buttons and D-pad
Press and release every available control. Analog buttons show their reported value.

Raw browser data
Axes and mapping
Use these values to spot unusual layouts. A blank standard mapping does not automatically mean the controller is defective.

Vibration check
Browser haptics are not available for every controller, connection method, operating system, or browser.

Diagnostic readings describe what this browser receives, not electrical measurements from the controller. Confirm important findings in the game or device where you plan to use the controller.
What this browser check can reveal
Many 8BitDo controllers support multiple platforms and input modes, so the same hardware can expose different button layouts, axes, names, and feature sets. Use the raw mapping panel to document the mode your browser currently receives.
Test all available buttons first, followed by sticks and analog triggers if your model includes them. If labels look wrong or triggers behave digitally, reconnect using the mode intended for your operating system and consult the model's official manual.
8BitDo produces many distinct models and revisions; this profile does not assume that every controller has sticks, analog triggers, vibration, or identical shortcuts. Evaluate only the controls physically present on your device.
Start with a known, stable connection.

A practical controller checklist.
- 01
Confirm the controller appears and the reported name or identifier is plausible.
- 02
Press and release every button, D-pad direction, stick click, bumper, and trigger.
- 03
Run the hands-off drift sample, then sweep both sticks through their full range.
- 04
Disconnect and repeat in the connection mode you actually plan to use.
- 05
Verify any fault inside a supported game or console before making a purchase or repair decision.
Compatibility is a chain, not a promise
Verify the exact model and input mode before following mapping advice.
8BitDo Controller Test questions
Why did the button layout change after reconnecting?
The controller may have started in a different compatibility mode. XInput, DirectInput, Switch, and other supported modes can expose different mappings.
Can this page configure 8BitDo profiles?
No. Use the official manual and supported 8BitDo configuration software for remaps, macros, firmware, and model-specific settings.
Why is a feature missing from my model?
The 8BitDo catalog includes retro pads, arcade controllers, mobile controllers, and advanced models with different hardware. Test only features listed for your exact model and revision.
