What type of connector does GROVE use?

I'm interested in wiring some old sensors so they're compatible with GROVE, so I first need to identify the connector so I can buy the housing and pins to crimp. It looks to be some type of JST connector, but there are many different sizes, each with incompatible pitches and a lot of retailers often advertise them incorrectly. Unfortunately, I can't find any documentation of the connector on Seeedstudio's site.

Here is the updated link on the seed website.


Also note that Digikey now stocks seeedstudio stuff.

It looks like the Grove connector is proprietary. I emailed Seeedstudio, and they directed me to this datasheet. Unless I'm reading it incorrectly, it doesn't appear to correspond to any type of JST connector, although it's similar. It has 2mm pin spacing, which would make it closest to the JST-PH type, but all the other dimensions are slightly different.

I believe this is the genuine article: Wire to Board connector > PITCH 2.00mm > 1125 Series

Good luck finding a vendor!

It is not a JST connector. There are ramps on the side of the connector that won't allow the grove/seeed cables slide into the connectors. After I shaved/cut off the ramps, to allow them to fit into the connector, I found that the pins are slightly offset in there vertical alignment. This appears to be a custom connector. However, if anyone knows better, I would be interested, but the answer is not JST.

  • @Greenonline Not really. Gerben made a statement, but that statement is obviously wrong as the pin pitch does not even match. – Chris Stratton Nov 8 '16 at 5:22
  • @ChrisStratton - I received some definitive information from Seeed's tech support, as posted in my answer. – Greenonline Nov 16 '16 at 10:48

The other answers are not correct. The Grove system from Seeed uses connectors according to these specifications,

  • Manufacturer: JST
  • Series: PH
  • Pitch: 2.0 mm
  • Available in 2-16 positions/contacts.

Note, however, that the actual connectors which Seeed is selling come from second sources/manufacturers, not from JST.

This connectors are very common under many other brands and names, however, the standard designation is JST-PH-2.0.

Manufacturer reference,

    The Grove cables with the latch clips will not work with JST PH. – Toybuilder Sep 21 '17 at 13:42

It is proprietary. It makes it hard to build your own custom length cables. But then if you are, you probably don't need Grove modules in the first place. I would use them more if I could build a cable. The JST PH 2.0 definitely doesn't work well, even if you shave it down. The PH also doesn't have the locking tab that the Grove connector does. It's interesting that some of the Grove boards have both JST PH 2.0 as well as Grove connectors for different purposes (e.g. LiPo battery connector)

These look like equivalents to the Molex Sherlock-series connectors (www.molex.com/molex/products/family?key=sherlock). I've ordered a Grove-compatible board that should get here Monday. I'll try connecting a Sherlock connector to it, and if I remember I'll give an answer back here as to whether it mates and locks properly. The pin pitch and pin dimensions are the same, I can tell that already, and it sure "looks like" a Sherlock connector.

    It mates with a Sherlock connector, but the latching mechanism doesn't latch. Oh well... – Richard Bruer Nov 21 '17 at 21:14

It's definitely not a jst-connector - please have a look at them here http://www.amazon.com/Seeedstudio-20-pack-Grove-Connectors/dp/B00BB0I7V2 (the seeed website seems to be down at the moment). I Eagle you would search for a TWIG-4P-2.0. These guys have 4PINs which are connected to ground and VCC + the data lines depending on the sensor you want to use.

Following up from Cerin's answer, as the link to the datasheet on Seeed's website appears to have expired, I also contacted the technical support team at Seeed.

They sent me, I assume, the same datasheet. Here is a link to it, 110990030-model, and here is a screenshot, should the link die in the future:

Grove connector datasheet

Along with the datasheet, I also received the following information:

11006005(OLD) -->110060161(NEW)

Grove - Light Sensor change to V1.2, which had another light sensor.

Others same.


Just some performance optimization.

From MCU's answer, and the linked eBay item for the Grove - SMD Universal 4 pin connector (10 Stück), the diagram below also shows the dimensions. However, it is quite clearly only a three pin connector, and not the four pin connector used in the Grove system:

Here there are GROVE connectors in SMD and a drawing is included: Grove - SMD Universal 4 pin connector (10 Stück).

    Unfortunately, the diagram in the link shows a three pin connector, and not a four pin connector as used by the Grove system. – Greenonline Nov 16 '16 at 10:47

I found the Grove Connector here: https://www.shotech.de/de/mechanische-komponenten/stecker/stecker-smd/

    Hi and welcome to SE.Arduino. Your answer is interesting but if your link dies, as it probably will do (as most links die eventually), then your answer will not be much use. If you could include a direct link to the product(s), an image & a brief description (and maybe a part number), then that would make your answer much more useful. See Are answers that just contain links elsewhere really “good answers”?. – Greenonline Aug 25 '18 at 22:25

    Also, please do not provide additional info in comments - edit your answer instead and add it to your answer, as comments are intended for queries and clarification requests. – Greenonline Aug 25 '18 at 22:26

    The answer in 2015 was a link-only answer which has died. Replacing it with another link-only answer is a rather temporary solution. Please add enough detail to your answer so that it will stand the test of time. :) – Nick Gammon Aug 26 '18 at 23:25
