J-Link EDU Mini

The J-Link EDU Mini is a stripped-down, budget-friendly model of the J-Link debug probe created for educational use. Even with its reduced size, it maintains the J-Link features of fast download rates into the internal flash of supported microcontrollers and the setting of unlimited breakpoints in flash memory.

The J-Link EDU Mini is available to educational institutions, private persons, and students who want to educate themselves in programming and debugging of embedded systems. Find out more about SEGGER’s Educational Partnership Program.

Key features

Software

All software is included free of charge. As a legitimate owner of a SEGGER J-Link, you can always download the latest software free of charge. Though not planned and not likely, we reserve the right to change this policy. Note that older models may not be supported by newer versions of the software. Typically, we support older models with new software at least 3 years after end of life.

Multi-platform

As a multi-platform solution, J-Link EDU Mini comes with the setup and control software for Linux, macOS and Windows. The MAC and Linux versions are fully usable, but limited to the following components:

Software and firmware updates are included. Similarly, use on all currently supported target devices, and any that will be added, is also included.

Licensing and support

You may use the J-Link EDU Mini for non profit educational purposes only! Non-profit educational purposes means that you may not use the J-Link EDU Mini and its J-Link software:

Any other use of the J-Link EDU Mini is prohibited and illegal! If there is any doubt if a certain use may be considered within the foregoing scope or whether your use of the J-Link EDU Mini applies to an educational situation, it is strongly recommended to get in touch and consult SEGGER prior use.

For clarification purposes: A student using the J-Link EDU Mini direct or indirect in a business or profit organization (e.g. company) is considered a violation of the scope of this agreement.

Please note:

J-Link EDU Mini does not come with support.

Flash Breakpoints

The J-Link EDU Mini license includes the Unlimited Flash Breakpoints in flash memory feature. Developers may set an unlimited number of breakpoints in flash memory helping to debug applications that run from flash memory.
