J-Link BASE / J-Link BASE Compact

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.

J-Link BASE Compact dimensions

The compact variant of the J-Link BASE is designed to mount securely and unobtrusively into development or end user equipment. The small size and two mounting holes enable placing the J-Link into existing equipment housings or to reserve space for direct-to-PCB mounting.

Typical applications are test fixtures that are used to automate firmware verification during development, or long-term test setups. It also can be used for integrated firmware reflash or service purposes inside end equipment, minimizing the number of tools that service technicians must carry around.
