+# Discontinued Autopilots/Vehicles
+
+:::tip
+For more information about PX4 project autopilot board support levels see: [px4.io/autopilots/](https://px4.io/autopilots/).
+:::
+
+This category is for discontinued autopilots and complete vehicles.
+These are no longer being manufactured, and may not be supported by their manufacturer.
+They are listed because you may be using them in an existing drone, and because they **may** still work with the head revision of PX4.
