• Description
• The J-Link line of JTAG programmers from Segger is well known for their top of the line debuggers. The J-Link BASE is a USB powered JTAG debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production(flash programming)purposes. The J-Link Base is a great option for those getting started with JTAG/SWD programming and debugging. Unlike the EDU Mini and the EDU this version comes with a license that allows you to build commercial products with it.
• 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.
