Overview
About J-Link BASE Compact
The J-Link BASE Compact is SEGGER’s entry-level debug probe in its smallest commercial form factor, functionally identical to the standard J-Link BASE with no code-size limits on debugging. It runs the same J-Link firmware as the PRO and ULTRA models and draws on the same device database spanning tens of thousands of devices. The licensed software add-ons, Unlimited Flash Breakpoints, J-Flash, and the Ozone debugger, come with the J-Link PLUS and above, or via SEGGER’s BASE-to-PLUS upgrade.
Supporting Arm Cortex-M/A/R and RISC-V architectures with download speeds up to 1 MB/s, the BASE Compact handles everyday development workflows with ease. RTT provides high-speed bidirectional communication for debug output, SWO enables trace-based profiling, and GDB Server ensures compatibility with every major IDE and editor.
At just 46 x 46 x 17 mm and 20 grams, with USB-C connectivity and two mounting holes for direct integration into fixtures, the BASE Compact fits into any workspace, test rig, or end equipment. Free software and firmware updates ensure long-term value and ongoing compatibility with new silicon releases.

Meet the GSAS Team at electronica India 2026, Stall H3.I45
electronica India 2026 opens on 16 September at BIEC Bengaluru. The GSAS team is on the floor all three days at Stall H3.I45, and this is who you will be talking to and what they can show you.
J-Link Is Now Validated by ST for StellarStudio
STMicroelectronics has fully validated SEGGER J-Link for StellarStudio, the IDE for its Stellar automotive MCU family, and put the probe into continuous validation at Le Mans. What that changes for the toolchain review on a Stellar programme, from GSAS, an authorized engineering partner for SEGGER in India.
An AI Agent That Drives the Debugger: SEGGER and Embedder Connect J-Link to the Loop
SEGGER has given an AI coding agent direct control of J-Link and J-Trace: flash, breakpoints, memory inspection and live RTT on real silicon. The loop only works if the probe can read target RAM while the core runs, and GSAS field engineers know exactly where that breaks first.
