This 4-wire cable is just over 150 mm long and is equipped with 4-pin female JST-SH connectors at one end and high-end Dupont male connectors at the other. Compared to the coarser JST-PH, they have a pitch of 1 mm instead of 2 mm, but always have a good locking feeling, while being easy to insert and remove.

This cable can be used with Qwiic cards, to easily connect sensors and drivers to cards with 0.1" female connectors or solderless cards. Or you can always solder directly to the ends of the header. When used with Qwiic, the colors are:

Red - Power supply 3.3VDC
Black - Mass
Blue - I2C SDA Data
Yellow - I2C SCL Clock Clock
