Professional 20-Pin to Dual 10-Pin JTAG/SWD Programming Adapter
The Tag Connect TC2050-2x10 adapter enables engineers to connect two TC2050-IDC 10-pin cables to systems requiring a standard 20-pin ribbon connection. This compact adapter board eliminates the need for dual 10-pin headers whilst maintaining full JTAG and SWD debugging capabilities.
