These are found in configurations.zip. There are no USB only versions anymore. These versions all work with USB or Ethernet. At this time, we do not recommend using the compat versions - you should use one of the many GCode Senders that work with grblHAL. If you need compatibility mode and other options, you will need to install the source from github and build it.
