Seeed Studio has created a very nice portfolio of devices centered around their grove connector. Recently, we started experimenting with the grove system ourselves as a nice way to quickly add sensors to CANZERO nodes in a NoCAN IoT network. Arduino even provides a nice MKR connector carrier board that fits perfectly well on our CANZERO nodes:
From afar, the Grove connectors look like the ubiquitous 4-pin JST PH connectors you can find everywhere, including cheap clones on eBay or Aliexpress. Despite being open-source, the Seeed Studio Grove system employs semi-proprietary connectors that can basically only be sourced through Seeed Studio and their resellers. Using JST PH would be a nice alternative. Unfortunately, a closeup look shows that apart from a similar 2mm pitch, they are two different incompatible connectors.
The picture below shows the Grove connector on the left and a JST PH clone on the right.
Sadly, you cannot plug a grove socket into a JST PH header, nor can you plug a JST socket into a Grove header. The through-hole footprints of the headers are compatible, so if you design a board with a Grove connector footprint, you can swap a JST PH connector when you populate the board. This footprint compatibility does not apply to the SMD version of these connectors.
Looking ahead
So what connector should we use for our future boards? Let us know what you think!

What standard IS it though? I've been searching for hours and hours, the closest I can find is just searching for 'grove' or 'hy2.0' but hy2.0 only comes up on china sites and I can't find the original standard/manufacturer?!
This is a semi-popular connector; for example, CompuStar remote starters have like 6-7 of them in all different colors, blue for antenna, black for programming, grey for telematics, green for shock sensors, red for digital sensors, etc. Trying to find colors myself as well. Don't know what standard to look for. Had any luck?

rv, over 4 years ago@Jai to the best of my knowledge, this appears to be a HY2.0-4P connector.

Noel Weiss, almost 2 years agoHi
Thank you for the quickly delivery to my office. When I view the package, I immediately saw that something was wrong with it, and when I opened it, the product was unfortunately broken. I made a photo so that you can see what I mean. https://photoscreenshot.com/proofdamageorder I am a regular customer, and I regularly order from your webshop. Hope we can solve this small problem in a professional way.
