J-Link EDU Mini
The small-size educational debug probe
The J-Link EDU Mini is a minimalistic version of the J-Link debug probe in a reduced form factor with identical functionality. It is designed for educational purposes and supports Arm and RISC-V based microcontrollers.
Overview
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.
