STLinkV2 Setup

STLink's are device programmers needed to load the USB Bootloader or for development and debugging. If your BlueSCSI has USB capability you do not need this.

Be sure to buy the "Clone" STLink V2 programmer - the official STLink programmer does not work.

Make sure the STLinkV2 is up to date - Latest Firmware

Connect pins SWDIO, GND, SWCLK, and 3.3v from the programmer to the Blue Pill.

NOTE: These are not the same as Serial ports.
