J-Link programmer

The J-Link line of JTAG programmers from Segger is well known for their top of the line debuggers. A low-cost J-Link for educational purposes, the J-Link EDU is identical to J-Link BASE and offers the same functionality. It has been designed to allow students and educational facilities as well as hobbyists access to top of the line debug probe technology. The J-Link EDU is a great option for those getting started with JTAG/SWD programming and debugging, but want a bit more power than the EDU Mini.

With a USB port on one end, and a 20-pin JTAG connector on the other end, just plug in the included cable and connect to your favorite ARM board, or just connect the pins you need, to get started.
