Customer Comments

  • Hey! Glad you’re finally carrying some stuff that also works with RC equipment! Now, how about some EC3 connectors, so I can power my Sparkfun projects from my airplane batteries?

  • 10 amps? Are you sure you want to stick with that story? That they’re specced for 3 is impressive enough.
    I have to applaud you on the direction of packaging one full connector’s worth of stuff as one item. This happens all the time, I want a 2 pin connection to a motor or whatever… just one! Or perhaps 2 or 3. Now I have to get male bodies, female bodies, and then male and female pins. This solves a big issue!
    One more detail… I use this tool to pre-crimp pins like this prior to soldering:

    It’s one of your products, and I use it all the time. But I don’t see it in the “Related Products' section for this part.

  • Anyone know where to get this in black or white? I need a few thousand sets for connecting lighting strings, and red is too garish for my application.

  • Are these polarity protected? Is it impossible to connect them backwards? There’s no pictures of the “other sides” of these.
