Overview

The Segger 8.06.13 is a specialized adapter board designed to sit between a J-Link debug probe and the target hardware. It breaks out all debug signals to accessible test points and includes jumpers for manual control over power and reference voltage lines. This tool is essential for engineers needing to monitor signal integrity or perform manual patching during the hardware bring-up phase.

Why Choose This Part

The board provides immediate physical access to every line in the standard 20-pin 0.1 inch J-Link interface without soldering. It simplifies the troubleshooting of communication errors by allowing engineers to break or reroute connections on the fly using standard jumpers and wires.

Applications

Signal Analysis
Using the integrated test points to connect logic analyzers or oscilloscopes to monitor SWD or JTAG timing and signal integrity.
Power Consumption Debugging
Utilizing the VTref jumper to isolate power rails or insert a current shunt for precise target power measurements.
Custom Signal Routing
Re-routing specific debug pins using the included jumper wires when target pinouts do not match standard ARM 20-pin layouts.

Key Specifications

Accessory Type Adapter Board
Utilized IC / Part J-Link

Getting Started

Connect the 20-pin socket to your J-Link debug probe and the 20-pin header to your target board using a standard ribbon cable. Ensure the jumpers for VTref and target supply are correctly positioned based on whether you are powering the target from the J-Link or an external source. Use the provided jumper wires to bridge test points if custom pin mapping is required for non-standard target headers.

Also Consider

J-Link 19-pin Cortex-M Adapter Segger Microcontroller Systems - Used when adapting the standard 20-pin 0.1 inch J-Link connector to the smaller 0.05 inch Samtec FTSH connector found on many modern ARM boards.
J-Link 6-pin Needle Adapter Segger Microcontroller Systems - A better choice for production environments where a physical header cannot be populated on the PCB.
