Features: Difference between Version 8 and Vetsion 9: Speed: Version 8 supports up to 10M, while Vetsion 9 supports up to 20M. Stability: Version 9 driver chip with voltages adaptived capability, when corded correctly, can automatically adapt to the targeted board voltages. 1.8-5.5V can be debugged, while the Version 8 can only debugging 3.30V , debugging 5V stability is poor. Version 8 can easily lose firmware. Many V8s have hunging up and need to rewrites the firmware. The Version 8 no longer supports some of the new CPUs, while the Version 9 supports almost all ARM CPUs. For embeddedlu system development engineers, electronics enthusiasts and related technicians. Suitable for laboratory research and development, product testing and field debugging and other environment.
