SEGGER Microcontroller J-Link PLUS & J-Link PLUS Compact Debug Probes
SEGGER Microcontroller J-Link PLUS and J-Link PLUS Compact Debug Probes are USB-powered JTAG devices that support many CPU cores. These debug probes are based on 32-bit RISC CPUs and can communicate quickly with the supported target CPUs. The J-Link PLUS debug probes are available in J-Link PLUS (100mm x 53mm x 27mm) and J-Link PLUS Compact (47mm x 40mm x 14mm) form factors. These debug probes are supported by all major IDEs, including Eclipse, GDB-based IDEs, and SEGGER Embedded studio. The J-Link debug probes are used for development and production (flash programming).

Assembly 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 BASE Compact 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.
