Sonar unit

Sonar gives you the ability to do altitude hold in close range with your Naze board.  Sonar is currently supported by Cleanflight firmware (not Baseflight yet).  There are no special commands - check the box in the configurator,  enable it on a switch and connect it up as shown.  On the older Naze Revision 5 boards, enabling sonar reassigns motor pins 5 and 6 to send and receive (see photo).  5v power is provided from the same place.  On the newer Naze Revision 6 boards, there are solder pads for trigger and echo.  5v power can still be obtained from the motor output pins as shown in the photo.  These are the SRF05 units which are supposed to be slightly more accurate than the SRF04.

Comes with wire set.
Measures 4.5x2x2cm
