1. Supports debugging of a full range of STM32 SWD interfaces. The 4-wire interface is simple (including power supply), fast and stable; the interface definition is directly marked on the shell! No need to flip through instructions! 2. Supports full range of STM8 SWIM download and debugging (common development environments such as IAR, STVD, etc. are supported); the supported software versions are as follows: ① XTW LINK ST Utility 2.0 and above ② STVD 4.2.1 and above ③ STVP 3.2.3 and above ④ IAR EWARM V6.20 and above ⑤ IAR EWSTM8 V1.30 and above ⑥ KEIL RVMDK V4.21 and above 3. Supports automatic firmware upgrade. The firmware has been upgraded to the new V2.J17.S4 before leaving the factory; 4. Add 5V power output, and the output I/O ports are protected, so you are not afraid of damage to LINK ST V2 caused by operating errors! 5. The interface uses pure gold-plated 2.54 pitch simple horn sockets, equipped with 20CM DuPont wire, which can handle different target board line sequences and provide flexible wiring; 6. Use the U disk aluminum alloy shell to protect the motherboard, which is easy to carry and is not afraid of static electricity or falling.
