Probes

Current firmware version: 2.15 (aka. v35).

NOTE: If you are using newer chips like CH32V317 or CH585, be sure to use the latest firmware.

NOTE: The firmware version is not the same as the version shown by WCH's toolchain. Because WCH calculates the version number by major * 10 + minor, so the firmware version 2.10 is actually v30 0x020a.

• WCH-Link CH549 - the first version, reflash required when switching mode
• WCH-LinkE CH32V305 - the recommended debug probe
• WCH-LinkW CH32V208 - wireless version
• WCH-Link? CH32V203
