Overview

The J-Link PoE is a specialized version of the J-Link Pro debug probe designed for remote debugging and test farm integration via Power-over-Ethernet. It features a built-in webserver for TCP/IP configuration and provides switchable power output to the target system via a USB-A port or the 20-pin JTAG header. With integrated licenses for Unlimited Flash Breakpoints and J-Flash, it provides a comprehensive out-of-the-box solution for professional embedded development.

Why Choose This Part

The primary advantage is the elimination of local power supplies and USB cable length limits by using PoE-enabled Ethernet for both data and power. It supports a wide range of MCU architectures and includes high-end features like VCOM functionality and direct-to-RAM/Flash downloading for high-speed development cycles.

Applications

Automated Test Farms
Ideal for CI/CD pipelines where multiple target boards are managed in racks and powered via existing network infrastructure.
Remote Field Debugging
Enables engineers to debug hardware located in hard-to-reach areas or different geographic locations over a local network or VPN.
Mobile Application Development
Provides a reliable debugging interface for mobile or battery-powered devices that require external power injection during testing.
Industrial Hardware-in-the-Loop
Integrates into industrial control cabinets to allow firmware updates and diagnostics without opening the enclosure via Ethernet connectivity.

Getting Started

Connect the probe to a PoE-enabled switch to power the unit and access the built-in web interface for initial network configuration. Use the Segger J-Link Software and Documentation Pack to interface with the probe via GDB, IAR Embedded Workbench, or Keil MDK. Ensure the target power requirements do not exceed the 300mA output limit when utilizing the switchable power-out feature.
