Features: brand new and high quality Differences between for J-link V8 and for J-link V9:1. Different speeds: V8 supports up to 10M (Jtag debug mode)/4M (Sdw debug mode), while for J-link V9 supports up to 20M (Jtag debug mode)/15M (Sdw debug mode). 2. Different stability: The driver IC of V9 has the ability of voltage self-adaptation. In the for case of correct wiring, it will automatically adapt to the CPU voltage of the target board. 1.8-5.5V cpu can be debugged, while V8 version can only debug 3.3v version cpu. 3. for J-link V9 main control chip adopts STM32F205, the firmware does not drop, and the hardware is upgraded to the latest version of V9.4 4. It can provide 3.3V voltage 0.8A current for the development board (pin 2) 5. Support standard Jtag interface and 2-wire Swd debugging interface. The speed can reach 20M (Jtag)/15M (Swd) per second. 6. Support debugging of all ARM chips, support Mdk or IAr, and other standard compilation environment IDE supported by standard for J-link. 7. Original firmware, fully automatic firmware upgrade, immersion gold process Specifications: Item: for J-link V9 Emulator Interfaces：Jtag；Swd Voltage： 1.2-3.3V ; 5V compatible Power： USB Jtag Speed: 12Mhz Size: approx 10.2 x 5.3cm/4x2.1in Package Includes: 1 PC x for J-link V9 Emulator Set note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand.
