The main control chip adopts STM32F205, without losing the firmware, and the hardware is upgraded to version V9.4.
It can provide 3.3V voltage 0.8A current for the development board (pin 2).
Support standard JTAG interface and 2-wire SWD debugging interface. The speed can reach 20M(JTAG)/15M(SWD) per second.
Support debugging of all ARM chips, support MDK or IAR, and other standard-supported compilation environment IDE.
Original firmware, automatic firmware upgrade.
Immersion gold technology, comparable to the original one.
V9 and V8 Difference :
The speed is different: V8 supports up to 10M (JTAG debugging mode)/4M (SDW debugging mode), while V9 supports up to 20M (JTAG debugging mode)/15M (SDW debugging mode).
Different stability: The driver IC of V9 has voltage self-adapting ability, and automatically adapts to the cpu voltage of the target board when the wiring is correct. The 1.8-5.5V cpu can be debugged, while the V8 version can only debug the 3.3v version of the cpu, while debugging 5vcpu has poor stability.
Some new CPUs are no longer supported by V8, while V9 supports almost all ARM CPUs.
Note: Shipped according to the selected configuration and emulator specifications!
