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)
