Adafruit STEMMA QT / Qwiic JST SH 4-Pin Cable - 400mm long

This 4-wire cable is slightly over 400mm or 15.7 inches in length, featuring JST-SH female 4-pin connectors at both ends. With a 1mm pitch, these connectors offer a latching feel while remaining simple to insert and remove, unlike the chunkier JST-PH connectors.

Designed for use with Qwiic boards, it enables seamless integration of sensors and drivers with 0.1-inch socket headers or solderless breadboards. The color coding for Qwiic includes Red for 3.3VDC Power, Black for Ground, Blue for I2C SDA Data, and Yellow for I2C SCL Clock.

Our design interleaves the data wire with ground and power to minimize cross-talk, though the cable's length might pose challenges for high-frequency signals such as 1MHz/800KHz or even 400KHz. If you encounter connection or data issues, consider reducing the I2C clock speed.
