The SEGGER J-Link EDU Mini is a compact JTAG/SWD debug probe for students and hobbyists working with Arm® and RISC-V-based microcontrollers. It delivers core J-Link debugging and flash programming functions in a small, minimal form factor.
Use it to halt program execution, read or write memory addresses, inspect an MCU in a live system, and quickly load code into the internal flash of supported microcontrollers. It connects over USB-C and presents a standard 9-pin 0.05-inch Samtec FTSH connector for the target interface.
This version includes a USB-C cable. Please note that the J-Link EDU Mini is licensed for non-profit educational purposes only, and it does not come with official direct support; the SEGGER community forum is available for user-to-user help.
Features:
- Fast Download Rates: Quickly load your code directly into the internal flash of supported microcontrollers.
- Unlimited Breakpoints: Set an unlimited number of breakpoints within flash memory for comprehensive evaluation.
- Modern Connections: Interfaces easily with your hardware using a modern USB-C port and a standard 9-pin 0.05-inch Samtec FTSH connector.

Jargon buster
Plain-language definitions for the technical terms used above.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- RISC-V
- An open processor architecture used inside some modern microcontroller chips. It matters because it affects the software tools, performance, and low-power features available for developing projects on the board.
- SWD
- Serial Wire Debug is a two-wire programming and debugging interface used with many microcontrollers. It matters if you need low-level access to program, recover or debug the processor board connected to this carrier.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
