J-TRACE, JTAG+ Trace Debugger for ARM



A JTAG debugger with Trace.  The J-TRACE can be used as a standard JTAG by using the JTAG cable or by swapping to the TRACE cable the Trace can be used.   NOTE both cables can be unplugged from the unit so you can make your own custom cables if required.


Also available a JTAG Opto Isolator and additional flash programming and break point software.
