Key Features
Overview
Overview
The SEGGER J-Link PRO PoE (SKU 8.12.28) is a professional JTAG/SWD debug and programming probe designed for automated “test farm” and remote workflows. Powered directly by Power-over-Ethernet (IEEE 802.3af), it removes separate power bricks and simplifies rack-scale deployment. The probe can supply power to the target either via the 20-pin debug header or its USB-A port, enabling remote power-cycling as part of CI and regression testing.
Performance & Tools
J-Link PRO PoE delivers up to 4 MiB/s download speed (target-dependent) with the standard J-Link software stack: J-Link GDB Server, Ozone debugger, J-Flash, and the Unlimited Flash Breakpoints licence for efficient debugging of code running from flash. A built-in web interface and DHCP make network configuration straightforward. VCOM (virtual COM port) provides convenient UART logging without a separate USB-serial adapter.
Compatibility & Family
Compatible with major IDEs on Windows, Linux and macOS and with a wide range of Arm® Cortex and other MCUs. Within the family, consider J-Link PRO (8.12.00) for non-PoE Ethernet/USB use, or J-Link ULTRA+ (8.16.28) for compact, high-speed USB with power measurement. For streaming ETM trace, see J-Trace PRO.
Why Consider It?
Engineers building reliable, scalable test infrastructure gain PoE power, remote target power control, and proven J-Link tooling—reducing setup complexity and accelerating automated validation.
How it connects
This J-Link uses SEGGER's standard 20-pin 0.1" (2.54 mm) JTAG/SWD connector, the same connector used on every J-Link and Flasher. For SWD you need VTref (pin 1), SWDIO (pin 7), SWCLK (pin 9), nRESET (pin 15) and GND (pin 4), plus SWO (pin 13) if you want trace output. Full JTAG, SWD, cJTAG and SPI pin tables, and the adapters for 10-pin 0.05" Cortex Debug headers: SEGGER J-Link 20-pin connector pinout.

Frequently Asked Questions
Have a Question?
-
What are related alternatives in the J-Link range?
For compact USB with power measurement, see the J-Link Ultra. For streaming trace and coverage, see J-Trace.
-
Can I access it remotely over the network?
Yes. Use Ethernet and SEGGER’s Remote Server for LAN/WAN access. PoE simplifies remote placement in racks and enclosures.
-
Does it work with my IDE?
J-Link integrates with major IDEs and debuggers on Windows, Linux, and macOS via the J-Link DLL or GDB Server.
-
Is ETM instruction trace supported?
For continuous ETM streaming trace, choose the J-Trace. J-Link can read ETB where available, but is not a substitute for the J-Trace.
-
Do I need special software licences?
Unlimited Flash Breakpoints, J-Flash, Ozone, and J-Link GDB Server are included in the J-Link Software & Documentation Pack.
-
How does PRO PoE differ from J-Link PRO?
Functionally similar, but PRO PoE adds PoE power and remote target power output for farm use.
-
Does it support SWD, JTAG, and SWO?
Yes. It supports standard Arm JTAG/SWD; SWO is available on supported MCUs for printf-style logging and event tracing.
-
How fast is programming?
Up to 4 MiB/s (target-dependent). This reduces turnaround between builds during CI and interactive debugging.
-
Can it power the target device?
Yes. When PoE-powered, the probe can supply target power via the debug header or USB-A, enabling scripted power-cycles during automated tests.
-
What makes J-Link PRO PoE suited to test farms?
PoE power plus switchable target power let you deploy many probes with one cable each and power-cycle DUTs remotely. For non-PoE Ethernet, see the J-Link Pro.
