Grove to STEMMA QT/Qwiic Cable (100mm)

Are you a maker in the midst of a STEMMA dilemma? This 100mm long cable is a fantastic chimera-cable fitted with STEMMA QT/Sparkfun Qwiic (JST-SH) on one end, and a Grove connector on the other.

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 colours are:

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

Revision History:

• As of August 20, 2021 we’ve changed suppliers for this cable, the clasp on the Grove ending has changed look slightly (but still works great to plug into Grove connectors).
