Well, NanoEdge AI Studio is free of charge for users of STM32. Users of MCUs with Cortex-M from other manufacturers can purchase a licence by contacting their local distributor or the nearest sales office of STMicroelectronics. As ESP32 is not based ...
Of course, the MC34063 can also be used to generate 3.3V, primarily only the resistors to the pin feedback need to be adjusted. The application in the data sheet focusses on 5V because it is already very old and 5V was the predominant supply voltage ...
Unfortunately, I have to inform you that both ST-LINK/V2 are clones, i.e. equipped with fake STM32F103 and stolen firmware. However, software of STMicroelectronics can only support original hardware. Ok, the hardware costs a few bucks, but the very e...
