Overview

The Segger 8.06.09 is a specialized adapter board designed to bridge the standard 20-pin J-Link connector to a 6-pin RJ12 modular interface. This adapter is specifically engineered for debugging target hardware that utilizes the RJ12 pinout common in Microchip PIC32 development environments. It ensures reliable signal integrity between the Segger J-Link debug probe and the target MCU.

Why Choose This Part

This adapter provides a secure mechanical connection and correct electrical pin mapping without the need for custom fly-wiring. It preserves signal quality for high-speed JTAG and SWD operations while adapting the standard 0.1 inch pitch header to the 6-pin modular RJ12 format.

Applications

PIC32 Target Debugging
Connecting a standard J-Link or J-Trace probe to Microchip PIC32 hardware using an RJ12 modular jack.
In-Circuit Serial Programming
Facilitating firmware uploads and real-time debugging on production boards with space-constrained RJ12 headers.
Legacy Tool Replacement
Allowing Segger J-Link probes to replace older RJ12-based debuggers in existing hardware workflows.

Key Specifications

Getting Started

Connect the 20-pin female side of the adapter to the J-Link probe and use a standard RJ12 cable to connect the 6-pin male side to your target board. Ensure the J-Link software is configured for the specific PIC32 device being used to handle the reset and data lines correctly.

Also Consider

J-Link 10-pin Needle Adapter Segger Microcontroller Systems - Used for connecting to targets without any soldered header by using spring-loaded pins.
J-Link 20-pin to 14-pin Adapter Segger Microcontroller Systems - Necessary for older TI or specialized ARM targets that use a 14-pin 0.1 inch pitch header.
