Getting started with STM32 development is a daunting task.
Prerequisites
Development Board
As mentioned earlier, there's a lot of different STM32 MCU variants and there's almost as many different development boards.
A very popular model was/is the so-called "Blue Pill" board:
There are different variants of these boards, but they are supposed to include a STM32F103 MCU. The problem is that almost none of them are. There are at least 6-8 Chinese companies making "clones" of the STM32F103 processor. Some of these are probably genuine MCUs with a properly licensed ARM core, that just happens to use the same memory map like the original.
ST-Link
The ST-Link is a device especially designed to flash and debug STM32 MCU's. ST can provide these at a reasonable price (< $20) but there are also a lot of Chinese "clones" available. The image to the right show a bunch of these clones.
While the original ST-Link devices provide additional features, the Chinese clones do get the job done and they have one benefit over the original that the pins on the device are clearly labelled. For some incomprehensible reason, ST decided not to label the pins on their device and that is really annoying in daily use.
Arduino
Before diving into using the Arduino IDE with STM32 development boards, I would like to stress that I think it is a horrible approach to learning.
