Features a 4-in-1 multifunctional development tool that switches four functions with a - key. In addition, 3.3V and 5V are also supported as power output. Supports the debugging of -MO/M3//M core chips with SWD interfaces, and an additional virtual serial port with a maximum baud rate of 20M, which can be used to observe logs during simulation. Supports debugging of RISC-V core chips (e902, e907, c906, etc.). It also supports a virtual serial port with a maximum baud rate of 20M, which can be used for simulation and log observation. When all serial ports are enabled, the for Combo 8 supports four virtual serial ports with a maximum baud rate of 20 Mbit/s, which suits almost all environments where serial ports are required. Among them, UARTO and UART1 can reach the highest baud rate of 20M, and UART2 and UART3 can reach the highest baud rate of 1M. Note:the appearance is slightly different, which does not affect the use.
