This 200mm long 4-wire cable is a fantastic chimera cable, equipped with STEMMA QT / Sparkfun Qwiic JST SH on one end and a STEMMA JST PH connector on the other end. You can grind down the middle key nub on the JST PH side to make it fit into a Grove connector.
The bulkier JST PH connectors have a pitch of 2mm, while JST SH (also known as Qwiic) has a pitch of 1mm. Both have a nice latching feel and are easy to insert and remove. Excellent for use with PyPortal, PyBadge, PyGamer, HalloWings, and anything else Adafruit has 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 another.
Please note that you need to be mindful of voltages on the power/signal pin when using this cable with only 3V Qwiic sensors!
- 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 a Grove or STEMMA host (5V) board and vice versa
- Warning: If you want to connect a Qwiic board (3V 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
