This 4-wire cable is a little over 400mm / 15.7" long and fitted with JST-SH female 4-pin connectors on both ends. Compared with the chunkier JST-PH these are 1mm pitch instead of 2mm, but still have a nice latching feel, while being easy to insert and remove.
, to easily connect sensors and drivers to boards with 0.1" socket headers or to solder-less breadboards. When used with Qwiic the colors are:
- Red - 3.3VDC Power
- Black - Ground
- Blue - I2C SDA Data
- Yellow - I2C SCL Clock
We've interleaved the data wire with ground and power to reduce cross-talk, but note that this cable is long for an I2C connection, so you may have difficulty using it with 1MHz/800KHz or even 400KHz signals. Try lowering your I2C clock if you're getting connection or data issues.
