NEW PRODUCT – 4-pin JST PH to JST SH Cable – STEMMA / Grove to QT / Qwiic – 200mm long


Are you a maker in the midst of a STEMMA dilemma? This 200mm long 4-wire cable is a fantastic chimera-cable fitted with STEMMA QT / Sparkfun Qwiic JST SH on one end, and Grove / STEMMA JST PH connectors on the other.

Chunkier JST PH connectors come with 2mm pitch, and JST SH (also known as Qwiic) are 1mm pitch. Both have a nice latching feel, while being easy to insert and remove. Great for use with PyPortalPyBadgePyGamerHalloWings, and anything else we made with a 4-pin JST PH connector for I2C.

This cable can be used with STEMMA or STEMMA QT / Qwiic boards to easily connect sensors and drivers from one board to the other.

Please note you will have to watch for voltages on the power/signal pin when using 3V-only Qwiic sensors with this cable!

  • You can use this to connect any Grove I2C sensor (3-5V) to an I2C host with Stemma QT or Qwiic connectors (3V)
  • You can use this to connect any STEMMA QT (3-5V) sensor to Grove or STEMMA host (5V) board, and vice versa
  • Warning: If you want to connect a Qwiic board (3V power only!) to a Grove or STEMMA hostmake sure the power switch is set to 3V

The colors are:

  • Black for GND
  • Red for V+ – For Qwiic boards, 3.3V. For STEMMA QT, 3 to 5V.
  • Blue for SDA
  • Yellow for SCL

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
