Segger J-LINK V8

  • €39.95


The Segger J-LINK V8 is the gold standard USB JTAG Emulator device used world-wide for flashing, programming and debugging ARM-based chipsets.

Bricked your Proxmark RDV2? This is the device you need.

Doing some serious development on any ARM-based platform, and tired of 'printf' plus an LED to debug? This is the device you need.

A proper JTAG/SWD HW debugger can make debugging more of a pleasure and less of a pain. It allows you to program your devices at the click of a button, read or write memory addresses or registers on a live system, temporarily halt program execution at a given location or condition, and much more. Essentially, it's a direct window into what's going on inside your MCU at any given moment, giving you a level of access and control that's not easy to replicate with other debugging methods.

Of the dozens (and dozens!) of debuggers out there (we have literally drawers full of them!), we chose the J-Link for a number of reasons:

  • It's USB based and uses a high-speed MCU internally, not an FTDI converter like most low-cost debugger. More debugging, less waiting!
  • It supports both JTAG (ARM7/9/11) and SWD (ARM Cortex), and has you covered for any core: ARM7/9/11, Cortex-A5/A8/A9, Cortex-M0/M0+/M1/M3/M4, Cortex-R4
  • It's toolchain, IDE and vendor-neutral, so you only need to buy one tool for all of your ARM needs and be done with it forever:
  • Support GDB-based debugging and flash programming on Linux, Windows and the Mac via the free GDB Server
  • Supports most major IDEs, including Keil, IAR Atmel Studio, Crossworks for ARM, etc
