J-Link BASE is a USB powered debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes.

JTAG/SWD debug probe with USB interface

J-Link BASE is a USB powered JTAG debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes.

J-Link BASE is available in two form factors with identical function: J-Link BASE and J-Link BASE Compact.

The J-Link debug probes are supported by all major IDEs including Eclipse, GDB-based IDEs and SEGGER Embedded Studio. For a complete list, please refer to Supported IDEs.
Including all models, more than 500,000 J-Links have been shipped so far, making J-Link probably the most popular debug probe for ARM cores and the de-facto standard.
