The dRonin Revolution target is the catch-all for may different betaFlight targets such as:
and from this thread I now learned the FuryF4OSD target as well..
The Deals & Sales thread lists lots of FCs known to work with dRonin Revolution target. Some, like the HGLRC clones, work other than the Buzzer and LEDs are inverted.
I found betaFlight's FRSKYF4 target.h cleanest and easiest to read.. dRonin's Revolution target works 100% on the XSRF4O. which makes the FRSKYF4 target.h a good one to compare other betaFlight target.h files to see if they are likely to run dRonin's Revolution target.
