It is adapter originaly designed as adapter for 6-pin headers which are present on most STM32 Nucelo and Discovery boards for debugging external microcontrollers. This adapter turns this ST properietry 6-pin connector to standard 10-pin 1.27mm pitch ARM Cortex Debug connector described, for example, at ARM Developer webste. Note that some newer boards exposes this standard connector and this adapter is not needed. Some STM32 boards also do not have this connector anymore (small nucleos and some modern boards). It is also usable as breakout for this connector since it expose SWDIO, SWCLK, SWO, and RESET signal from this tiny connecter on more easily accessible pinsockets.
