Description The WCH-LinkE module can be used for online debugging and downloading of WCH RISC-V architecture MCU, and can also be used for online debugging and downloading for ARM chips with SWD/JTAG interface. A JTAG interface is provided to support four-wire connection (TMS line, TCK line, TDI line and TDO line) to extend the JTAG interface for a computer to operate CPU, DSP, FPGA, CPLD and other devices. Through its USB2.0 full-speed interface, it can be connected to a computer host. It is plug and play. Connected to target chips by the debugging interface, it can be used for debugging and programming. Features: Two 3.3V/5V power supply outputs are supported Supports USB to TTL serial port function Supports RISC-V chip single-wire/dual-wire downloading and debugging Supports downloading and debugging for ARM kernel MCU with SWD/JTAG interface Supports automatic firmware detection and upgrade 3.3V/5V output power supply is controllable Automatic power-off protection Red and blue LED indicator lights make it easy to check the working status Supports a host computer to switch working mode via one key Specifications: Data bit : 8 Stop bit : 1 Check digit : None Flow Control : None Baud rates : 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 230400, 460800 and 921600bps
