ST-LINK V2 eight POINT: 1. The use of aluminum alloy U disk Shell installed internal motherboard, easy to carry, safe and reliable! 2.Interface definition directly on the shell, at a glance, convenient and practical! 3. 5V, 3.3V at the same time to provide external, convenient for you to connect to 5V and 3.3V Target Board 4.The use of the shell character laser, laser engraving, do not fade off! Permanent Clarity! 5.The internal motherboard with 500MA self recovery fuse. Protect the computer motherboard! 6. Red and blue two-color led, easy to observe St-Link V2 working status! 7.Distribution 4 with DuPont Line, easy to deal with different target line order! 8. External packaging using anti-static bag, automatic sealing machine sealing packaging. Features: 1, support a full range of STM32 SWD interface debugging, 4 wire interface simple (including power), fast, stable work; Interface definition shell directly marked! No need to read the instructions! 2, support a full range of STM8 SWIM download debugging (common development environment such as IAR, STVD and so on); The supported software versions are as follows: XTW Link St Utility 2.0 and above STVD 4.2.1 and above STVP 3.2.3 and above IAR Ewarm V6.20 and above IAR EWSTM8 V1.30 and above Keil Rvmdk V4.21 and above 3, support the automatic firmware upgrades, the factory firmware has been upgraded to the latest V2. J17. S4; 4, increase 5V power output, output I/O mouth are protected, not afraid of operation error caused by link St V2 damage! 5, the interface uses the Pure copper gold-plated 2.54 spacing simple horn seat, with the 20CM DuPont Line, may deal with the different target plate line order, the nimble wiring; 6, use U disk aluminum alloy Shell to protect the motherboard, easy to carry, not afraid of static, not afraid to fall and fall. 7, with the information package, including: 1, XTW link St V2 drive; 2, Keil MDK (4.60) development environment (and other common development environment) 3, IAR STM8 (1401) development environment (and other common development environment) 4, STVD STM8 development environment (and other common development environment) 5, a number of classic STM32 data (including a large number of examples of source code and video tutorials) 6, a number of classic STM8 data (including a large number of examples of source code and learning experience) Specification: Type: ST-Link V2 Emulator Downloader Material: Plastic and Metal Color: as the picture shows Weight: Approx.12g/0.4oz Package list: 1 x XTW Link St V2 A 1 x 20CM cable 1、support a full range of STM32 SWD interface debugging, 4 line interface simple (including power), fast, stable work; Interface definition shell directly marked!
