ST-Link with JST adapter?

I inherited a board that has a SM06B-XSRS-ETB JST connector for the SWD port.  I believe they were using an ST-Link programmer. 

Does the ST Link programmer come with an adapter cable that has the male side of the connector?  Or is there a cable available?

 

I would like to think they chose a standard connector for the design but I am not having luck finding one.

That's not a standard SWD connector, so there won't be  a standard cable or adaptor.

it doesn't seem that they were that helpful.

      People / Companies tend to do things in ways that are convenient to them. Either a depth of existing inventory, or familiarity.

      Amazon has JST connector / cable kits, I'll use these when not keen in investing in crimping tools and parts. Helpful when fiddling with UAV boards or flight controllers.

      To add to Andrew's observation, Tag-Connect has grown popular as a means to do SWD connection on STM32 and similar platforms.

        I remember meeting the inventor when he was over here first promoting it back in 2010!

        Easy. Just get a new ST_Link V3 and wire up anything to its open contacts.

          not that it's hard to wire up a custom connection to a standard St-Link:
