Overview

The Target Supply Adapter provides an adjustable supply voltage for target boards. It has a standard 20-pin 0.1" socket towards the J-Link debug probe or Flasher in-circuit programmer, and a standard 20-pin 0.1" header on the target side and can directly be inserted between the J-Link or Flasher and the debug cable maintaining a 1:1 connection of all debug signals. The target voltage can be adjusted from 0.8 V to 3.6 V by replacing a single resistor on the adapter.
