Product Description
SEGGER J-Link PRO High-Speed Debug Probe – Ethernet and USB JTAG/SWD Emulator for Professional Embedded Development
This used SEGGER J-Link PRO is a professional-grade JTAG/SWD debug probe designed for high-performance embedded system development . As the most widely used line of debug probes on the market, J-Link provides unparalleled speed, extensive feature set, and broad CPU support for ARM, RISC-V, and many other architectures .
The J-Link PRO is the enhanced version of the standard J-Link, adding an Ethernet interface alongside USB connectivity . This allows the debug probe to be used remotely over a network, making it ideal for distributed development teams, large production environments, or scenarios requiring electrical isolation between the host PC and target .
With download speeds up to 4 MB/s and a target interface speed of up to 50 MHz, the J-Link PRO delivers exceptional performance for both debugging and flash programming . It supports unlimited flash breakpoints, Real-Time Transfer (RTT), and includes free licenses for professional tools including Ozone debugger, J-Flash programmer, and RDI/RDDI .
Condition Note: This unit is untested and sold as-is. It is a pull from surplus inventory. No USB cable, ribbon cable, or original packaging are included unless specified. The probe is sold as hardware only; software licenses are included free of charge from SEGGER upon registration .
