4 Pin JST-SH Cable (Qwiic, STEMMA QT, Qw/ST)

4 pin JST-SH (1mm pitch) cables, available in a variety of lengths and configurations.

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!

Notes

• Adafruit also have a range of STEMMA boards, which use a larger JST-PH connector. These cables are only compatible with smaller STEMMA QT range.
• * Note that the new 500mm cables with the black shrouding have different coloured wires:
  • Black - GND
  • Red - V+ (3.3V for Qwiic, 3-5V for STEMMA QT)
  • Green - SDA
  • White - SCL
  If you're using long cables and are having trouble making an I2C connection or transmitting data reliably try lowering your I2C clock speed!
