ST link SMT32

The programming and debugging tool for STM32 microcontrollers, connecting over SWD to flash firmware and — more importantly — to debug it properly, with breakpoints, single stepping and live variable inspection. That is the real advantage over Arduino-style development, where debugging usually means adding print statements and guessing. Also programmes STM8 devices. Works with STM32CubeIDE, PlatformIO and the Arduino IDE's STM32 core. Full debugging with breakpoints and single stepping; Flashes STM32 and STM8 microcontrollers; Works with STM32CubeIDE, PlatformIO and Arduino; Compact USB stick format with jumper leads
