Note: Like all of our Airbot products, this is the genuine original Airbot board - not a clone.

The omnibus series of flight controllers are known to be the best all in one integrated flight controller, using the best selection of sensors and parts at a great price and small form factor. Now the latest addition to the series uses the performance STM32 F405 MCU. The omnibus F4 uses the MPU6000/ICM-20608 IMU over SPI for the super fast gyro updates (up to 32Khz) to keep up with the fast F4 MCU, allowing you to run your betaflight/iNav control loop insanely fast. This gives you the extra edge when racing your FPV quadcopter.

The AB7456 OSD chip (an upgraded MAX7456) allows for direct configuration and updates directly within betaflight. This OSD chip uses much less power than the older MAX7456 OSD Chip, but the main benefit is that it can be configured directly within betaflight, no need for an external FTDI, or jumper switches. In addition the omnibus F4 includes a high performance 5V, 1.5A STM L78 voltage regulator which help filter the power and adds voltage protection to the board.

Omnibus Versions

  • The V6 omnibus has quite a few changes:
    • New firmware target (OMNIBUSF4FW) - after flashing go to CLI and type set gyro_to_use = second , and save to get the IMU working.
    • 5x UART Ports
    • 5V 1A and 8V BEC for FPV camera
    • Current source jumper selecter (see manual for more information)
  • The V5 omnibus includes a current source selection jumper (see pinout below for more details), also the omnibus f4 v5 uses a new 8 pin Sh 1.0 Socket to make connecting a 4in1 ESC much easier. This is compatible with up to 6S batteries.
  • The V4 omnibus main feature is that the solder jumper to selected between PPM/SBUS is no longer needed. The board also features some minor hardware revisions to increase the boards robustness even more.
  • The V3 fixes some of the LDO problems of the V2, so now you can power this board directly from your battery (up to 4S Lipo)

Key Features

  • Tantalum Capacitors added for noiseless gyro reading
  • Solder pads added for SmartAudio and Camera Control (next to Video pads)
  • Added an 8v BEC and LC Filter for the camera and VTX power
  • This board now has 5 UART ports
  • New style layout

Specifications

  • STM32 F405 MCU
  • SBUS input (no PPM input support)
  • 6PWM output
  • Only 36x36mm, mount holes 30.5x30.5mm
  • BMP 280 Baro
  • SPI Sensor MPU6000/ICM-20608
  • 128Mbit Flash
  • Powered directly from 2-6S Lipo (v5 only)

Kit Contents

  • 1x Omnibus F4 Flight controller

We do not include any pin headers with this board, but we do sell them separately on our website.

Zadig Drivers

If you have problems connecting to the board, or uploading new firmware the best fix is to use the zadig driver tool.

  • Push BOOT button on the flight controller.
  • Plug-in the USB cable (the red LED should not be as bright as normally).
  • Fire up Zadig and hit "Options" and then "List All Devices".
  • From the list choose "STM32 BOOTLOADER".
  • Under "Driver" choose "WinUSB" on the right and hit "Reinstall Driver".

For more information check out our zadig driver tool tutorial

Omnibus F4 V6 Pinout

Omnibus F4 V5 Pinout

The V5 omnibus includes a current source selection jumper (see pinout below for more details), also the omnibus f4 v5 uses a new 8 pin Sh 1.0 Socket to make connecting a 4in1 ESC much easier.

Omnibus F4 V4 Pinout

This v4 pinout is for people who still use the older version. The notable feature of the V4 board is that the SBUS/PPM solder selector jumper has been removed, now you can just connect your receiver to J7 and select the type within betaflight.

Omnibus F4 V3 Pinout

The pinout was kept here for previous customer still flying on the V3 omnibus.

Using SBUS/PPM/DSM

There is a known bug with betaflight that can sometimes prevent you from switching between SBUS and PPM. You need to first select serial RX and sbus in the configuration tab, save. Then go turn on serial RX on the UART 6 port in the ports tab and save. Then go back between the two to make sure the settings have been saved correctly as sometimes it does not save properly.

Inverted and non-inverted SBUS

  • SBUS/PPM (J7) header (uart6) This is for inverted signal receivers; has fixed inverter that can not be turned off (by cli command sbus_inverter=on/off)
  • RX1 (on J2) (uart1), These are for non-inverted signal receivers.

Spektrum DSM

  • DSM connector (on J8). This is for non-inverted signal receivers, and is equivalent to RX1.

Arming problems:

  • If you are certain that your board is set up correctly yet it refuses to arm, try raising the gyro noise limit in the CLI using this line: "set gyro_calib_noise_limit = 120"

My Dog's Favorite Balls
Size: 2 Count (Pack of 1), Style: Pack of 2
My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!

The Dog LOVES IT!
I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!
