Recently brought 2 pcs STLINk V3 MODS. downloading all the documents from st site i didnot find right information(whre is SWD,SCLK, pin located in STLINK V3 MODS) so that i can connect to my target bare metal board of STM32F103 Series MCU. Very much time wastage buy doing fake stlink v2 , from authentic source i brought STLINK V3 mods in a hope that i can programe and debug. Help required.No fruitfull video, no fruitfull document available throughout of internet.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
