Overview
Stlinkv2 is an open-source printed circuit board by dltech, from the dltech/stlinkv2 repository on GitHub. It is a 2-layer board with 60 parts on 53 nets, routed with 603 tracks and 19 vias.
It is built around the BZX84-C5V1. Its parts include 24 resistors, 15 diodes, 13 capacitors, 5 connectors and 2 ICs. It belongs with the STM32 boards of this library.

ST-link V2 schematic and PCB in kiCAD with initial firmware through UART.
- PCB templates for prototyping at home are photoresist.svg and lut.svg, also you can convert PCB to any of appropriate formats using KiCAD.
- As you seen above, for this solution you do not need any other st-link, you need only usb-uart adapter.
- When you got a board, pull up pin 44 BOOT0 to Vbus by R4 resistor, so after power connect the MCU starts up from the UART bootloader.
- Power up board by USB and connect it to your PC through UART by RX and TX pads.
- Write dummy firmware from STLinkV2_bin.zip using the flasher utility (ST UM0462).
- Return pull down resistor to pin 44 BOOT0 (change location of 10-100K resistor from R4 to R5 place).
- Then connect it to USB and write the firmware from ST using upgrade utility stlink-V2.J21.S4.zip. Now you got a working st-link clone.
On the linux using the Virtualbox software this method is working too.

Questions
What parts does the Stlinkv2 use?
60 parts, built around the BZX84-C5V1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stlinkv2 KiCad files?
From the dltech/stlinkv2 repository on GitHub, at the commit this page was made from: the board is wire/stlinkv2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stlinkv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask dltech before reusing the design.
