* - not connected on the device, need to modify ST-Link: cut STM8's tracks for nRST & SWIM signals to become instead STM32's nRST (STM32 pin 18) & SWO (STM32 pin 31) signals
** - not connected on adapter board

PDF schematic & board:
Solder jumper can be used with Original ST-Link to connect IDC-20 pin 19 VDD (3.3V) to rest of 3.3V (pins 1-2). Jumper should remain open for use with J-Link, it has 3.3V output on pin 1, while pin 19 has 5V, might damage your board!
Changes:
- Changed SWD pin header to match Nucleo ST-Link V2-1 pinout
- Fixed Blue Pill / Black Pill board (STM32F103C8T6) connector to be non-mirrored
- Added a solder jumper (NO) between pin 19 and pins 1-2 for Original ST-Link V2 to provide 3.3V power
- Added power indicator LED
Supported interfaces:
- Chinese ST-Link V2 dongle
- Chinese MX-Link dongle
- J-Link / Original ST-Link V2
- Tag-Connect (TC2030-IDC)
- Nucleo original ST-Link V2-1
- Blue Pill / Black Pill board
Known issues:
- none
PDF schematic & board:
Changes:
- Added Blue Pill / Black Pill board (STM32F103C8T6) connector
Supported interfaces:
- Chinese ST-Link V2 dongle
- Chinese MX-Link dongle
- J-Link / Original ST-Link V2
- Tag-Connect (TC2030-IDC)
- SWD pin header
- Blue Pill / Black Pill board
Known issues:
- Blue Pill header mirrored, need to plug in board upside down (chip facing down)
- Original ST-Link V2 does not provide 3.3V on pins 1-2 (it is VDD_Target input instead), need to connect pin 19 to pins 1-2 on IDC-20 connector with external wire. J-Link works okay, as pin 1 has 3.3V output.
