JST-SH Cable (Qwiic, STEMMA QT, QW/ST) – Male to male (200mm)

These 4 pin JST-SH cables are great for hooking up microcontrollers, breakouts or other boards with Qwiic or STEMMA QT connectors (or as we like to portmanteau it, Qw/ST).

Whether you need crocodile clips for quick setup, DuPont-tipped jumper wires for plugging into breadboard, or just a straight cable to link two Qw/ST connectors we've got you covered!
