About this item

The WeAct Studio WCH-Link.W is a powerful, wireless + USB dual-mode debugger and downloader designed for RISC-V and ARM Cortex-M microcontrollers. Based on WCH's latest debugging architecture, this tool supports both SWD (Serial Wire Debug) and JTAG interfaces, making it highly compatible with a broad range of chips including CH32V, CH5xx, and STM32 series MCUs. One of its standout features is the 2.4 GHz wireless communication, which enables cable-free debugging and programming over short distances—ideal for clutter-free workspaces or embedded systems that are difficult to access. It also supports USB wired mode, offering flexibility in various development environments. WCH-Link.W integrates seamlessly with toolchains like Keil MDK, IAR, OpenOCD, PlatformIO, and WCH IDE, enabling flash programming, breakpoints, step execution, and real-time variable inspection. Firmware upgrades are supported via USB, ensuring future-proof compatibility with new devices and protocols. Compact and easy to use, this debugger is an ideal companion for developers working on embedded systems using WCH or ARM chips, offering reliable performance in both wired and wireless modes.
