STLINK/V3MINIE design files

Are the design files of this board available from ST website? I'd need to know where can I get 3.3V and tie it to pin1 (Target VCC) off CN14. Then I'll be able to power the target MCU through this connector. Please check next post for further information:

thanks in advance,
Gaston

Hello,

The design files are not available.

The V3MINIE is not designed to power the target MCU. It is only regulating the 5V coming from the USB port for its own purpose.

The onboard regulator is limited and trying to power the target MCU might disrupt the debugger functionnality.
