Hi Arduino Community

Hi im new to Arduino, so i just got a quick question.

I need to connect the D6T-1A-02 to the Arduino UNO.
To do that i would need a JST wire, but im not if it should be with the JST 4-pin 1,25mm or 1,00mm. Thinks its 1,25 but need to be sure.
If you know which one, maybe a good site to buy them from.

The connector cited in the datasheet you linked is a GHR-04V-S, and Digikey lists it as a 1.25mm spaced connector.
Why not buy it from Digikey?
