Overview

J-Link Supply Adapter

The Supply Adapter provides a manually adjustable I/O voltage from 1.2 V to 5.0 V and eliminates the need for VTRef from the target board. It connects between a J-Link or Flasher and the target while maintaining the debug signal connections, reducing the number of connections required on the target.
