problems downloading the pro mini

hello everyone! does anyone know how to upload a sketch to an arduino pro mini?

You need to select the appropriate board before uploading. Arduino pro mini is one of the options:

I understood that. Do I need to connect the pro mini via a programmer or via another arduino?

It would be the same for XOD as for Aduino IDE. From https://docs.arduino.cc/retired/boards/arduino-pro-mini/, it says early on “A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board.”

thank you very much!
