I have a Raspberry Pi 3 and a display that has only RCA as inputs. Please help me connecting the Raspberry Pi to the display so that I get both sound and visual.

a display that has only RCA as output

I presume you mean 3 female inputs, 2 for audio and one for composite video, which in North America are generally red, white, and yellow.

The 3.5mm jack on the Pi 3 can be connected to this as it includes a composite video line. Jacks like that can be used with a normal 2 channel audio only cable, or a 3 channel one such as that shown below (the two ends are from the same cable).

enter image description here

Notice the three bands on the 3.5mm jack, one more than a standard stereo plug (these are actually separators as I believe in both cases there is an additional pole for ground, which is the sheath on the RCA end). These are commonly available at electronic stores or online (search for a "3.5mm to RCA video cable").

Beware as mentioned here (thanks Milliways) some of these cables are intended for camcorders and have one of the rings on the 3.5mm jack swapped; those will not work. So don't get a cable that is intended for use with camcorders!

  • I am far from clear that this is what the OP is asking. There are 4 connections, and most of the commonly available cables are unsuitable. See raspberrypi-spy.co.uk/2014/07/… – Milliways Mar 3 '17 at 11:03
  • @Milliways Yes, as I point out in the last paragraph the visible rings (sometimes black) are separators and there are actually 3 channels on a normal 3.5mm jack, one for ground, hence 4 for video, exactly as described in the link you provided, and the cable shown there is exactly the same as the one shown here. There is another form of video using RCA connectors that is 3 channels for video (instead of one) and 2 for stereo, but this is much less common (and I suppose not compatible with the pi). – goldilocks Mar 3 '17 at 11:17
  • I will edit in the bit about the camcorder cables, but I would presume those are the exception and not the rule. – goldilocks Mar 3 '17 at 11:19

To be sure, you can get a cable from Adafruit to ensure that the cable is for RCA display product (versus RCA output product).
