SWD programmer and debugger for STM32 and STM8 โ with 4 jumper wires
The cheapest way to flash and single-step an STM32: this USB-stick ST-LINK V2 connects to the SWD header of a Blue Pill or any STM32 board with four wires (3.3 V, GND, SWDIO, SWCLK) and provides programming and full debugging through the ST-LINK driver. It also supports STM8 over SWIM and can power the target with 3.3 V. Works with STM32CubeProgrammer / CubeIDE, Keil, IAR, PlatformIO and OpenOCD. The metal shell has a pin map printed on it. Four 20 cm jumper wires included; the plastic end cap colour is random.
