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 STEMMA JST PH connectors on the other. You can sand down the center-nub key on the JST PH side to make it fit in a Grove connector.

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 PyPortal, PyBadge, PyGamer, HalloWings, 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 host, make 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
