 This is newer variant of JTAG which requires only 2 signal lines instead of 4+.
 But but aware, they both have different pinouts on the connector.
+The second one offers 2 more power ports at the expense of JTAG TDI and TDO/SWO.
-These JTAG adapter are based STM32F1xx ARM Cortex M3 micro-controllers.

 And ironically enough I in turn use them to program and debug STM32F1xx ARM Cortex M3 micro-controllers.

+It supports JTAG, SWD, SWO, RTCK, and voltage reference.
+That makes it the most complete JTAG adapter I have.
