The Open-Q
TM
410 Platform includes a 20-pin JTAG header (J602). The header is a male, keyed, 0.05” header
as shown in the figure below. Part number is SAMTEC FTSH-110-01-L-DV-K-P. This JTAG header is intended
to be used with a Lauterbach 20-pin JTAG module. A conversion cable is required to connect the 0.05” pitch
JTAG header to the 0.1” pitch JTAG module.
