Omnibus F4 + OSD flight controller specs and hookup diagrams
BetaflightF4 is the follow up design to the very popular BetaflightF3. Following in the same path as Betaflight F3 we have kept a very similar footprint in terms of design with a few added modifications. 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.

Betaflight F4 Flight Controller.Change PIDs, adjust common configuration parameters, and change video transmitter channel and power level, all using your transmitter sticks and goggles.
This means that there is no need to soft-mount the board itself.
ICM with 6-axis gyro and accelerometer. Can run at up to 32 kHz. No need to run a separate vBat wire for voltage monitoring; the Kakute F4 AIO monitors voltage directly from the battery power lead.
On-board regulators output 5v at up to 1. Top View. Bottom View. Size View. Kakute F4's bidir inverter is designed with mosfet. But there are some special XSR receivers, who's input capacitance are higher than the normal, it may cause the smartport waveform distorted. The waveform don't drop to 0v during low period. See the following picture. Change a resistor on the KakuteF4 from 4.
As of we are still shipping orders as normal. BetaflightF3 is the flight controller designed to use every possible feature of Betaflight. More than the last half year has been spent in development. This board features a 3A power draw giving users extra room for added attachments through uart ports. The six layer PCB is a more expensive design approach but was needed to give the ability to have a PDB that was capable of having wiring pads on both the top and bottom of the board.
By using the six layer design we were able to increase the size of the pads and work around all the components all the while giving esc connections in the corners of the board rather than bunching all connections on either the top OR the bottom.
The team at betaflight have been hard at work developing DSHOT and this board is also compatible with the latest release. Email: Technical Support Order Support. GetFPV Benefits. This website requires cookies to provide all of its features.

Customer Services.Right now many agree that the Omnibus F4 series is one of the best F4 flight controllers you can buy for the money. There where a few issues with the first few versions, but since V4, they now work flawlessly and this is the flight controller I recommencement to everyone. Unless you are a seasoned veteran of FPV racing scene, using an omnibus can be daunting as there is not much documentation.
This guide will try to clarify everything. Looking for the Omnibus F4 V6 Guide?
Read it here. The omnibus F4 V5 can be powered directly from your flight battery 2s-6s since the built-in regulator will convert the voltage down to 5V. However, if you prefer you can also power it via a cleaner direct 5V power supply. This is helpful if you have particularly noisy motors that cause a lot of interference on the circuit.
The most common method to power the omnibus is direct via the battery supply. The board version 5 can handle up to 6S Lipo voltage directly on the Vbat pin on J5 as shown below. See RAM Power section below. The only thing you should take note of is the solder jumper to choose between the current sensor or ESC telemetry. More on the solder jumpers later in this guide. This configuration lets you use the built-in current sensor on the typhoon 4in1 ESC or any other 4in1 ESC that has a current sensor.
Connecting your receiver to the omnibus is not much different from any other flight controller. Using FRsky smart port telemetry via softserial Smart port telemetry as shown in the connection diagram green wire will let you send telemetry data back to your Taranis radio. However, the problem on the omnibus is that the UART1 ports do not have a serial inverter built in.
To overcome this you simply need to use soft serial which emulates the inverter via software. Port 11 is for softserial 1, and port 12 is for softserial 2. So if you wanted to assign softserial 2 to another pin such as UART6, or the LED pinyou could assign port 12 to the corresponding pin you got from the resource command. Spektrum DSM All of the omnibus boards have a dedicated Spektrumconnector which has the signal, 3v supply and ground as needed for your Spektrum satellite receiver.
DSM connector on J8. This is for non-inverted signal receivers and is equivalent to RX1. The omnibus has some solder jumpers, the jumpers on J16 and J20 allow you to select between the current sensor, or ESC telemetry or to output 5V on the servo rail. J20 allows you to enable 5V output or ESC telemetry on the servo rail. This is ideal if you are flying a fixed-wing plane and want to power your servos from the omnibus.How-to setup Betaflight F4, (BFF4) TBS Crossfire v2, Blheli32 Telemetry, smart audio, camera control
If you are flying a quadcopter using BLheli32 ESCthen you will want to enable telemetry on the servo rail.Thanks to Mick Ward for sharing his findings on the ins and outs of this FC. It also has a linear 5v regulator on board so the FC can be powered by mains. It is not without some limitations however. It would seem that if the 5v rail gets overburdened the FC can brown out or reset or perhaps in the worst cases blow the 5v reg. The 5v linear reg is rated for 1.
Also the higher input voltage the greater the losses to heat. If you decide to power a string of LEDs and your camera or other accessories off the FCs 5v rail you may find it struggles to cope. But there is a simple workaround. Above that you can see the OSD connection pins. The RAM pins do nothing unless you configure them to output 5v, which is not recommended for the reason discussed above, and also because if your voltage slumps below 5v it can lead to your camera dropping out. Its for this reason and to reduce load on the linear reg that we recommend you send 12v regulated to the camera and vtx.
Connect your VCC direct lipo connection to the Vbat pins, taking note of the correct polarity. These connections will be enough to get you into the air, once you have set up all your particulars in Betaflight.
If you want to run more devices off 5v you have a couple of choices, but first and foremost you need your vbat connection for measuring voltage in Betaflight. So to continue using vbat for this without overheating your 5v reg you can remove the reg and power the FC from an external 5v regulator via the motor pins in the traditional fashion. Depending on what equipment you have on hand you have a couple of choices.
If you have a heat gun you can heat the chip up until it falls off. For those who dont have a heat gun this method works well too. Using a set of sharp snips cut the two bottom legs away from the chip. With a clean hot iron tin the top of the IC with a little solder.Anyone who uses Betaflight should be familiar with the Betaflight F3 flight controller.
FPVModel has just upgraded it and put a F4 processor in it. In this review we will also check out other changes. To learn more about flight controllers, here is our guide.
The Betaflight F4 FC comes in a plastic box, with only the board itself, and a 10cm servo cable. It would be nice to see some low ESR capacitors or even soft-mount rubber bobbins included. The biggest change seems to be the processor.
Finally they replaced the SD card slot for Blackbox with a flash memory chip. However just like many other F4 flight controller, you have to perform the uninverted Smart Port hack to get SPort Telemetry to work. F4 is a more powerful processor than the F3 for detail differences between different STM32 processors, check out this post. But is it worth the upgrade for existing Betaflight F3 users? I would say it depends heavily on how much you care about running the fastest looptime and the latest BF features.
Since the release of Betaflight V3. This is mainly caused by the new Dynamic Filter feature, which is too much for F3 processors.

F3 users have been asked to lower their looptime from 8K to 4K when running Dynamic Filter. Therefore if you want to run the fastest possible looptime i. Just very odd issues I have no clue why. This is the only combination that works for me. Is there A way you can look at the Noxe f4 flight controller. It will not read voltage and I have many of these with the same problem.
Unfortunately I have a problem and can not find a way to solve it. I checked the following steps: 1. The wiring on the FC. It works. The I connected th FC to the Betaflight configurator. No succesess.
Do you have any idea to solve my problem? Could you please explain when to select which UART?So the S drone could save much weight for a faster fly experience. This FC is available for 1S whoop drone also. The Frsky D16 unstable connection issue is totally resolved since Betaflight 3. Here are the solutions we provide for you. The binding procedure is reversed as usual.
No need to click the bind button when power on. Some pilots would complaint that it is definitely not a long range FC. It looses signal with my transmitter far too often and for what appears to be no reason. This issue is often caused by the location of the antenna. You should keep the antenna away from the FC board to get a stronger signal.
For example, run the singal upwards. For detailed information of other external receivers, please find out in our support page. Yes, we have tested this FC board with motors on Beta75X.
