Key features
High Download Speeds
J-Link Pro PoE offers download speeds of up to 4 MB/s, ensuring that project development moves forward smoothly and reliably, with minimized download times.
Real Time Transfer
J-Link Pro PoE offers Real Time Transfer (RTT), which provides a simplified path for information to travel when a application is running. Users can also easily monitor changes in operation.
Broad CPU and IDE Support
J-Link Pro PoE works with an extensive range of microcontrollers and integrated development environments (IDEs). It enables users to connect their selected microcontroller with their favorite IDE.
Supported Devices
The list of supported manufacturers, families, devices, and SoCs includes tens of thousands of devices in hundreds of device families.
Use Cases
J-Link Pro PoE is ideal for creating test farms, and it contains robust features for efficient management of large-scale test environments. A test farm is a network of embedded system nodes - such as evaluation, prototype, and production boards - that is remotely accessible for testing and debugging.
By connecting these systems to a J-Link Pro PoE, developers and testers can manage and debug hardware without direct physical access to each device. This setup not only improves the testing process, it also supports automation and faster testing cycles, and enables tasks like regression testing and continuous integration. A test farm using J-Link Pro PoEs may consist of multiple test devices of the same type or entirely different devices.
Communication Testing
When testing communication protocols such as WiFi, ZigBee, or Matter, large-scale test setups are crucial for ensuring reliability and performance. A test farm using J-Link Pro PoE provides a way to test devices under various conditions and ensure that they can handle interference and high traffic volumes
Compatibility Testing
A test farm is essential when testing new firmware updates or compiler changes across multiple devices. With J-Link Pro PoE, tests can be run simultaneously on different platforms, saving time and ensuring that updates are compatible with all devices in the test farm
J-Link Technology
Unlimited Breakpoints
Set as many breakpoints as you need in internal or external flash. Debug thoroughly, even when hardware breakpoints run out.
Monitor Mode
Keep essential system functions running while debugging. Perfect for real-time applications that must stay responsive.
Power Profiling
Measure and optimize energy consumption with high sampling rates and 50µA resolution. Ideal for battery-powered or energy-harvesting devices.
Tool Set
J-Link Pro comes with a versatile suite of software tools that enhance its performance and flexibility for debugging and programming. Utilities such as J-Link Commander, J-Link Configurator, and J-Link Remote Server make it a powerful and convenient tool for any development setup. Below are selected highlights from this tool set.
J-Link Pro supports SEGGER Embedded Studio as well as virtually all Integrated Development Environments (IDEs), ensuring maximum flexibility in any development setup.
It integrates seamlessly with SEGGER's Ozone debugger, providing a powerful environment for performance analysis, instruction tracing, and code optimization.
J-Flash enables programming of microcontroller internal and external flash memories. Exceedingly versatile, it runs on Microsoft Windows, Linux, and macOS, and it supports Cortex Arm, RX, and RISC-V devices and cores.
J-Link DSK
J-Link Device Support Kit (DSK) allows silicon vendors and users to add debug and flash programming support for new devices. A new device typically requires a flash loader and, in some cases, a script defining special connect and reset sequences.
DSK includes the SEGGER flash loader as well as a collection of example script files for devices that require special handling.
J-Link SDK
J-Link Software Development Kit (SDK) enables the integration of J-Link and J-Trace support into custom applications. It is used in professional IDEs, such as SEGGER Embedded Studio, to enable direct debugging via J-Link/J-Trace, as well as in customized production utilities. Available for Windows, Linux, and macOS, the SDK can be used with nearly any programming language or solutions.
Software
All software is included free of charge, as are licenses for all J-Link-related SEGGER software products, such as J-Link Unlimited Flash Breakpoints, Ozone, RDI, and J-Flash.
Buyers Guide
Customer Support
J-Link Pro PoE comes with one year (12 months) of Basic Support. Beyond that, SEGGER's Extended Coverage gives users the option to extend the hardware warranty and Basic Support for one additional year (12 months) or two additional years (24 months). These options are only available at the time of purchase, either through the Web Shop or upon request; adding coverage at a later date is not possible.
