What style JST connectors are on the Motor Shield Rev3?

[cybercom]

I'm trying to find the proper JST female connector style for the Arduino Motor Shield Rev3 plugs. The documentation simply says Tinker Kit.
They are three pin with 2mm pitch spacing and when I search for connectors online, there are a gazillion different styles. Some of them have protrusions and flanges that will obviously prevent them from interfacing with the jacks on the AMS3.
Does anyone know the specific JST style required???
Thanks in advance for your assistance!

The JST-PH and JST-PA have a 2mm pitch.
here are a few sharp pictures. Maybe it helps.

Thank you for your response.

Unfortunately, the only pix that look like the connectors for the Motor Shield are the Molex KK series, and they are too widely spaced at 2.54mm and wider according to the Molex website.
They are the proper physical construction however.

As mentioned in my forum post, all the JST connectors in the pix have extra protrusions that would interfere with connecting them to the shield.

I'll have to keep searching.

Hi!

I found a vendor with the proper connectors - Robot Mesh located in Bellvue, WA, USA. They have both 3-pin & 4-pin versions so I'm good to go.

Thanks again for your assistance.

As you saw, these are usually only referred to as "TinkerKit!" connectors.

I have done quite a bit of searching and still never found any useful information about sourcing these things on their own.

TinkerKit! as a business entity seems to have disappeared around spring 2014, yet Arduino continues to put these connectors on their hardware even though there doesn't seem to be any ecosystem of modules to connect them to.

The part number shown in the Braccio Shield schematic (just the one I happened to grab, I didn't look at other schematics) is WA254-03S-IN, but I don't find any information about this on Google.

You can find claims on the archived TinkerKit! of availability of the connectors for sale on the Arduino Store, but they are not available there:

But the good news is that the pitch and pin size makes them compatible with a standard "dupont" connector, so there is no problem with making connections to them.

Good News Everyone!

I found a supply at a company called Robot Mesh. They have 3-pin and 4-pin pre-wired female-to-female and 3-pin male headers available.

I agree that, with all the thousands of connector types available ( I get dizzy at DigiKey!), the Arduino universe could use something a little easier to find.

Thanks for your response & I hope the link helps you.

I'll keep the dupont concept as an alternative.

Are you sure about the 2mm pitch?
When I look in the Eagle zipfile of the motor shield and measure the pin distance I get 2.54mm

In that case a Dupont connector will do.

You're right!

Good to know. I'll revisit the Molex site.

Meanwhile, I've found a source for TinkerKit pre-wired connectors at Robot Mesh.
They have various lengths of 3-pin & 4-pin female units and separate 3-pin male headers.

Thanks for following up. Much appreciated!

Following up from the Molex site:

These connectors are KK254 series and are available pre-wired to the connectors.

You might have to search for a distributor, but I've included a relevant Molex link:

Molex Connector Part Number - 217797-1031

Hope this helps!

Thanks to all who contributed to this conversation.
