The SEGGER J-Link EDU is a powerful hardware debugger designed for ARM-based platforms, identical to the more expensive J-Link BASE model but intended strictly for non-commercial educational use.This USB-based debugger supports both JTAG (ARM7/9/11) and SWD (ARM Cortex) interfaces with compatibility across a wide spectrum of ARM cores including ARM7/9/11, Cortex-A5/A8/A9, Cortex-M0/M0+/M1/M3/M4, and Cortex-R4.Key features include: High-speed USB connection with an internal MCU for faster debugging compared to FTDI-based debuggers. Vendor and toolchain neutrality supporting GDB-based debugging and flash programming on Linux, Windows, and Mac through the free GDB Server. Compatibility with major IDEs like Keil, IAR Atmel Studio, and Crossworks for ARM. Preloaded flash programming algorithms for numerous MCUs, continuously updated by SEGGER. Fast execution of breakpoints and flash programming. The EDU version is limited for use strictly in non-profit educational purposes and personal projects; commercial uses require the purchase of the full J-Link BASE debugger.Included in the package: J-Link EDU with standard 20-pin 0.1" male connector 20-pin 0.1" target ribbon cable USB cable Note: This product is no longer stocked by Adafruit. A recommended alternative is the SEGGER J-Link EDU Mini - JTAG/SWD Debugger.
