CL Racing F4S

Summary
CL Racing F4S Flight Controller AIO with built in PDB and BetaFlight OSD . New Version. Introducing the latest development in F4 AIO flight controllers. CL Racing F4S designed by Cheng Lin.

This board is designed to fully embrace all the features of Betaflight. In fact, this design is ahead of Betaflight, in this case, because it is designed to be fully functional when Betaflight 3.2 will be released. Everything works, except the buzzer, which will work when betaflight 3.2 is ready. It's a programmable micro buzzer.
