This 4-wire cable is 50 mm / 1.9" long and fitted with JST SH female 4-pin connectors on both ends. Compared with the chunkier JST PH, these are 1 mm pitch instead of 2 mm, but still have a nice latching feel while being easy to insert and remove.
Use it with Qwiic or STEMMA QT boards to easily connect sensors and drivers from one board to the other. The cables are symmetrical, so don’t worry about which side goes where!
