<p>Your NUCLEO board has an on-board JTAG development interface. All your development action is through this JTAG part, usually a STM32-F013 chip. This interface also provides a "FTDI" USB Host interface with your board that usually connects to UART 2 (See NUCLEAO schematic.) That guy wasn't using a NUCLEO, or was just clueless. I have some STM32 projects on my website: <a href="http://www.merkles.com" target="_blank">www.merkles.com</a>. I prefer to use the STM32-CUBE, since it configures all the peripherals for you into source code. After that, there are multiple environments to use. I believe the majority of people use STM tools. I continually run into roadblocks when trying to use MBED. They are great for "Hello World", but after that, you'll likely get stuck. My favorite "Go To" NUCLEO is the NUCLEO-F446RE. The processor is packed with peripheral support, and it's relatively cheap. The folks that don't have any money usually head toward the "Blue Pill", a small STM32-F103RB development board. But, after you get JTAG adapter, and FTDI serial added, the price becomes close to the NUCLEO-F103 board. I HATE the Blue Pill since it doesn't provide a reset signal from the target processor to the JTAG interface. This means you have to play games with the reset switch to get software to load to the target each time. BTW, MicroPython runs great on the F446RE.</p>
