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"

Good value for solar watch
Color: Black/Orange
Nice watch! It is plastic like but it is solar. No indiglo button only a little luminous on the hands so you don't want to wear it in tje dark and expect to check the time. 45mm case is good size for my wrist and the band works good also, Not too long not too short. Overall a good watch with no problems

Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.
