J-Link ULTRA+ is a JTAG/SWD debug probe designed for ARM/Cortex. It is fully compatible to the standard J-Link and works with the same PC software.
Based on the highly optimized and proven J-Link, it offers even higher speed as well as target power measurement capabilities due to the faster CPU, built-in FPGA and High speed USB interface.
