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

This 4-wire cable is approximately 400mm (15.7 inches) long and fitted with JST-SH female 4-pin connectors on both ends. Compared to the larger JST-PH connectors, these have a 1mm pitch instead of 2mm, offering a secure latching feel while being easy to insert and remove.

The cable is compatible with Qwiic boards and facilitates easy connection of sensors and drivers to boards with 0.1" socket headers or solderless breadboards. Wire color coding for Qwiic is as follows:

• Red - 3.3VDC Power
• Black - Ground
• Blue - I2C SDA Data
• Yellow - I2C SCL Clock

The data wire is interleaved with ground and power wires to reduce cross-talk. However, due to the length of this cable, it may experience difficulties with I2C signals at higher frequencies such as 1MHz, 800KHz, or even 400KHz. Lowering the I2C clock speed may help in case of connection or data issues.
