The Holybro Kakute F4 is an all-in-one (AIO) flight controller, with Betaflight OSD, PDB, and data-flash for Blackbox built in. It has an F4 processor, so you can run all the major Betaflight features without over-working the CPU. It supports simultaneous SBUS, SmartPort telemetry, and SmartAudio. Finally, it's got an innovative method of mounting the gyro that means you don't have to separately soft-mount the board.
Oh, and did I mention, I wrote the manual for it? So it's got an awesome, detailed manual that anybody can follow to wire up the FC.
