Sorry, it was not correct description.

   Original ST-Link/V2 has 20-pin connector for JTAG/SWD and 4-pin
   connector for SWIM.

   ST-Link/V2 clone has 10-pin connector only, but it has additional
   +5V source (which is not available in the original version).

For FST-01, it is OK.  But I have a concern for general case.

For example, FSM-55 has NRST pin so that SWD programmer can impose
MCU-reset (this is different than JTAG/SWD-reset functionality).
FSM-55 requires NRST pin connected to the programmer, because FSM-55's
application goes into suspend mode.  I'm not sure if ST-Link/V2 clone
works for FSM-55.  If clone's pin of #9 works as NRST, it will be OK.
But it seems that the NRST pin and SWIM_RST is different in the
original ST-Link/V2.

Someday, it would be better to make our own programmer.
