WireViz — ARM Debug Adapter, 10-Pin Cortex to 20-Pin JTAG

An adapter from the 0.05-inch 10-pin Cortex Debug connector to the 0.1-inch 20-pin ARM JTAG connector: VTref, SWDIO/TMS, SWCLK/TCK, SWO/TDO, TDI and nRESET each land on their 20-pin counterparts (1, 7, 9, 13, 5 and 15), with the two Cortex ground pins carried on separate conductors to grounds 4 and 6.
