Description: Simple breakout board for the RCA connector. Use this breakout (shipped bare) to allow breadboard or SIP access to the super-common RCA video/audio jack. All three pins are broken out.

Bare PCB only

  • Hey guys…. your RCA jack is upside down in the last picture. Shouldn’t it be on the other side?

    Cheers,

  • Why three pins? And where did you get BRL, SPR, and BRK from? I guess BRL is barrel, and thus ground. The middle plug (signal) has continuity with SPR. so is BRK the switch? But what are these names? Is SPR “spear”?????

    • The schematic uses the terms break, spring, and barrel.

    • Still no idea where the names came from, but to replicate Crono’s comment: BRL to ground, BRK to signal. SPR, on the other hand is tied to BRK (signal) when disconnected, and left floating when connected! Can anybody see the flaw in this (sarcasm)? Isn’t it standard, for example, in DC barrel jacks, to have the switch go to ground? With the switch going to signal, it will be VERY hard to tell whether or not it is plugged in. Or am I mistaken?

      • I believe that the purpose of such a layout would be to send the video or audio signal elsewhere in the circuit (maybe a coaxial converter) if nothing is plugged in.

      • So, the SPRing pin is connected to the BaRreL pin while there’s no cable connected to the jack, and disconnected when we connect a cable in the jack. Did I understand what you’re saying?

  • Please provide the EAGLE layout for this RCA jack footprint (not necessarily the breakout board). I saw no RCA in the current SparkFun library. Maybe I’m missing something. I should have gotten out the calipers to check the footprint I used before sending a proof board to BatchPCB.

    • In the library it’s under POWER_JACK. The actual footprint & schematic seems to be POWER_JACKRCA. There’s also POWER_JACKRCA_LOCK.

  • For anybody using these breakout boards… BRK is the signal, BRL is Ground. If your attaching these to a CMOS camera make sure that BRL shares a common ground with your camera.
