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

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.
  • * If you're having trouble making an I2C connection or transmitting data reliably using the long 500mm cables try lowering your I2C clock speed!

I purchased this because I am working with 2 Raspberry Pi 5s, and only want to use 1 monitor, 1 mouse, and 1 keyboard for both boards. My keyboard is cordless, so I can put the dongle in the femail connector, and one of each mail plugs into the two Pi's. One toggle switch moves control between the two Pi's so I can go back and forth. The only small thing is it takes a bit of time after the switch is changed to get control, BUT it is much easer than easier then moving the plug in dongle. I love it!

A short tidy cable ideal if used in conjunction with the QT 5 port hub allowing multiple sensors (TOF,9-DOF,Temperature/Humidity/Pressure sensors to name just a few). Keeps the wiring short/tidy/reliable.

A great cable if you main Pico Main PCB has the Qwiic/Stemma QT connector fitted (like Pico Plus2/w or Pico Lipo by PiMoroni). I'm not a great fan of the DuPont connectors as they are realy untidy and sometimes unreliable if the mess of wiring is disturbed (like your Robot car rolling over).
