    Overview

    Image of a SEGGER RAFF Adapter. It features a small green circuit board with two rows of metal pins on top and a black connector at the bottom. The text "SEGGER RAFF Adapter" is printed on the board, indicating its purpose for hardware connections.

    The RAFF Adapter is a Right Angle Female to Female adapter. It is a 1:1 adapter and therefore does not change the pinout and can be used as a replacement of the standard IDC ribbon cable. A compact debug or programming solution can be achieved with a J-Link PLUS Compact, a J-Link BASE Compact, or a Flasher Compact, and the RAFF adapter plugged into a straight/vertical PCB pin header on the target application board.
