SEGGER J-Link ULTRA+

J-Link ULTRA+ is an ultra fast debug probe for JTAG/SWD. It is 100% compatible with J-Link PLUS, just faster. Unplug your J-Link PLUS, plug in your J-Link ULTRA+ and enjoy the faster download speeds. It simply works!

J-Link Debug Probes ➦

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.
