Betaflight F4 Flight Controller
Betaflight F4 is the follow-up design to the very popular BetaflightF3. Following the same path as Betaflight F3 we have kept a very similar footprint in terms of design with a few added modifications. The F405 has replaced the F303 to allow for lower CPU loads.
We have eliminated the 5v/3.3v jumper and added two separate connection points, one for SBUS and one for spektrum users. The jumper still remains for the battery voltage/5v connection for connecting your camera. While wiring the board it is recommended to get power for your VTX either from a different 5v source on the board or if using a higher voltage VTX power it from the battery input coming into the PDB. Running ground loop at AGND with GND wires from camera and VTX is still recommended to give the cleanest video signal.
Another small design change to this board was changing the BEC, this change takes the recommended 5v 2A current limit and drops it down to 5V 1.5A, its a small change but one that we opted for in order to use a more reliable BEC.
BetaflightF4 now comes with telemtry pads for BLHeli32 ESCs these pads are located between the signal and gnd pads for the ESC connections.

- Before soldering or mounting any flight controller, connect it to your PC and verify operation
- Incorrect soldering techniques will damage this board and void warranty. Please use the correct sized tip, temperature and technique. Temp controlled soldering irons (such as the TS100) are available for under $100 and will make soldering much easier.
- Lifted pads are a result of incorrect soldering techniques or excess mechanical pressure and will not be covered under warranty.
- USB ports must be handled with care, breakage of usb ports are not covered under warranty
- Always use a smoke stopper before powering your build for the first time.
