-EV3 MicroPython is built on top of ev3dev, which means that a sensor
-may be supported even if it is not listed in this documentation. If so, you can
-use it with the ``Ev3devSensor`` class. This is easier and faster than using
-the custom device classes given above.
-
-To check whether you can use the ``Ev3devSensor`` class:
-
-    * Plug the sensor into your EV3 Brick.
-    * Go to the main menu of the EV3 Brick.
-    * Select `Device Browser` and then `Sensors`.
-    * If your sensor shows up, you can use it.
-
-Now select your sensor from the menu and choose `set mode`. This shows all
-available modes for this sensor. You can use these mode names as the ``mode``
-setting below.
-
-To learn more about compatible devices and what each mode does,
-visit the `ev3dev sensors`_ page.
