Adafruit STEMMA QT / Qwiic JST SH 4-Pin Cable - 300mm long

This 4-wire cable measures slightly over 300mm or 11.8 inches in length and is equipped with JST-SH female 4-pin connectors on both ends. Compared to larger JST-PH connectors, these feature a 1mm pitch rather than 2mm, yet retain a secure, latching feel while being easy to insert and remove.

Ideal for use with Qwiic boards, this cable facilitates seamless connections between sensors and drivers and can be easily integrated with boards featuring 0.1" socket headers or solder-less breadboards. When connected with Qwiic, the cable's color codes are: Red for 3.3VDC Power, Black for Ground, Blue for I2C SDA Data, and Yellow for I2C SCL Clock.

The design includes interleaving data wires with ground and power to minimize cross-talk. However, this cable's extended length may present challenges for I2C connections operating at 1MHz/800KHz or 400KHz; lowering the I2C clock speed may resolve connectivity or data issues.
