In order to create the version of Sensor Tutorial, which uses the PlatformIO IDE I need to verify my understanding of the process of using the SWD Programmer & Debugger. This is a self imposed task, which might be of value to other community members.
I believe that each successive upload of a “sketch” requires resetting the MCU, process explained in Programming Swan without the STLink-V3Mini)
Press and hold the
BOOTbutton on the Swan, press and release
RESET, then release
BOOTto cause the Swan to jump into its boot loader mode.

This reboot is required to allow that the connection between my development machine (micro USB cable , green marker 1) be used in a dual mode (interactive and programmatic, where the default mode is _interactive_.
IS THE TEXT ABOVE CORRECT???

Debugging with PlatformIO IDE
I plan to use STLINK-V3MINI hardware, expecting that it will provide me the ability to use the MCU in both interactive and programmatic mode, without having to reset the Swan MCU every time, I change the code (firmware)
The STLINK-V3MINI is a stand-alone debugging and programming mini probe for STM32 microcontrollers, like the Swan SwAN MCY Use the JTAG/SWD interfaces to connect to the Swan via its onboard connector for simple programming or debugging.

Is the STLINK-V3MINI on Image 3 functionally the same as STLINK-V3 Modular in-Circuit debugger and Programmer for STM32/STM8 sold on Amazon? What would be the benefit of using one over the other?

Is there a detailed description how to connect this hardware to the Swan board ? Just looking at Image 3 or Image 4 does not give such information.
