+## Connections
+
+### Naze32
+
+Connect a supported buzzer directly to the BUZZ pins.  Observe polarity.
+
+### CC3D
+
+Buzzer support on the CC3D requires that a buzzer circuit be created to which the input is PA15.
+PA15 is unused and not connected according to the CC3D Revision A schematic.
+Connecting to PA15 requires careful soldering.
+
+See the CC3D - buzzer circuir.pdf for details.
