I wish it were that easy. There are many "4-pin 2.0mm pitch male connectors” (e.g. JST PH), but they’re not compatible with the proprietary Grove connector. Adding “Grove” to the search doesn’t help either as it comes up with female headers or people looking for the same thing I am. I have only found one vendor in Europe, but shipping is cost prohibitive.
@tkudog, if you’re able to get a result from that search (other than shotech.de), please post a link.
