Hi there.
I want to download my bin file to one of my customized board ( target STM32G030F6P6).
The problem is the debugger pin CN1 of Hardware board MB1441 has 5V input but my one has 2.8 V in debug connector.
Kindly recommend a solution for voltage level shifting.
And also share Hardware board MB1441 schematic.

CN1 of the STLINK-V3SET has CMOS 3.3V interfaces, not 5V.
The B-STLINK-VOLT board extension is a 1.65V-3.3V voltage adapter board for the STLINK-V3SET.
The entire toolset is not open source, so the schematics are not publicly available.
Hope that answers your questions?
Regards

Peter,
Thank you for clarification.
Do you have CN1 pin map? Let me know. Figure out the location of 1.5 to 3.3v source.

You can find the pin map of CN1 in UM2448, section 8.2.1.

CN1 connector is not providing 3.3V.
I succed it when I put 3.3V externally.
