      Does anyone know the availability of the Grove 6-Pin Screw Terminal Stereo Jack Adapter? I found one place that’s selling it for $7 but the shipping is $25. I currently have two of the plug in adapters but need the screw in type.

      Thanks

      Since that has 3 ground lines, wouldn’t a 4-pin work?

      I don’t know, I’m just going off of the parts list that I have. It may, since the sensor only has 4 wires.

      Perfect. Go with a 4 pin. The 3.5 mm jack only has 4 pins/connections over the length of the jack. Here’s a photo that might help. You can find a lot about how these are mapped for audio (left, right, mic, ground) and they are mapped differently for iPhone vs other manufacturers.  https://cdn.sparkfun.com//assets/parts/7/5/4/6/11570-04.jpg

      We used to sell the 6-pin screw terminal boards on Amazon, but don’t anymore.  We do offer a 5-pack in our EnviroDIY ship page if you want to buy 5 all at once:  https://www.envirodiy.org/product/envirodiy-grove-6-pin-screw-terminal-adapter-pack-of-5/

      Otherwise as Beth said, you might be able to use a regular 4-pin screw terminal board that is widely available from lots of different vendors.  We made the 6-pin version specifically for interfacing with the Campbell Scientific OBS-3+ turbidity sensors that have 6 wires and require 3 ground connections.  It’s easier to use this 6-pin board with those sensors than trying to fit 3 ground wires into one single screw-terminal on regular boards.

      Your sensor probably has a power wire, ground, and two data lines (analog or digital).  If you have anything other than that, you might want to double-check before connecting it to the Mayfly.

      The link Beth posted above is a 4-position, 3.5mm headphone jack adapter board made by someone else.  We have a 3-position headphone jack in our shop, but you don’t need a headphone jack if your sensor has bare wires on it.  You’d only use a headphone jack if you bought a sensor that comes with a 3.5mm plug on the end of the cable, like what Meter Group does.

      Thanks but I can’t use the jack end. I have to be able to plug in a jumper wire that then plugs directly into a board.
