This is a replacement cable for the Promira™ Serial Platform. One 34-pin end has a locking friction ramp to ensure good connectivity with the Promira platform while the other 34-pin end is designed for easier connection and removal to your project board. For more advanced or power intensive applications, the 34-pin cables are recommended because they provide additional connectivity to your project, enabling features not available with the 10-pin cables. Please note, specific pins and functionality are determined by the applications licensed on your Promira Serial Platform.
