There's a number of different ways to flash STM32 devices. One of these is to use ST's own ST-Link devices.

There are multiple benefits of using one of these ST-Link devices rather than a plain serial dongle:

  1. The device need not be restarted in flash mode (Boot0)
  2. Programs can be debugged on the device

The official ST-Link as seen above are relatively cheap (< $20) and there are Chinese copies available (haven't tried those).

The most common option are these:

They are Chinese knock offs and they run the official ST-Link firmware.
