Today I bring you one more flight controller, this will not be a true review, but will be more like a hands on. After the F4 flight controllers the market is changing for the F7 flight controllers and this is one of the examples that we have in the market today. I’m talking about the OMNIBUS AIO F7 from Airbot. So let’s see all the features and the improvements that we find on this FC.
This time I skipped the unbox chapter because this FC came in a simple antistatic bag without any cables or connectors, all you get is the flight controller.
With a STM32F745 processor we know just by the name that this will be the high performance flight controller. Plenty of power, this processor will let the developers to “spread their wings” of imagination, one of the downside to use this processors is his size, placed at the center of the FC it takes around 50% off the 36x36mm PCB size. This processors bring another great feature that we lost on the F4 flight controllers the capability to inverte the UART signal by software, so on F4 FC you only have one UART for Sbus because the other ones are not inverted, in this FC you can plug your receiver into any UART using the Sbus protocol. On this board you only get 4 motors output and 3 UARTs and one SPI or 2UARTs, one I2C and one SPI.
Once you look at this FC the first thing you will see is the huge F7 processor, but with a more carefull look we could see two gyroscopes, yes Airbot introduced two gyros on this tiny PCB they are the old and well known MPU6000 and also the ICM-20608-G a newer version of MPU6500, this last gyro has the capability to sample at 32kHz, much higher sampling than the old MPU6000 that sample only at 8kHz. Higher sampling isn’t allways a good thing, because can capture more vibrations and send this inputs to the motors causing even more vibration. Besides we have two gyros on this board, but we only can choose one at a time and not a merge of this two to work like redundancy.
This board also a AB7456 IC for OSD and card bay for blackbox record, to power the VTX and camera you get a voltage regulator capable of 5V at 1A not so much amperage, but should be enough to power everything you need.
- STM32F745 CPU;
- Dual gyro system: MPU6000 at 8kHz and ICM-20608-G at 32kHz;
- 3 UART available: UART1, UART3 (shared with I2C port) and UART6;
- OSD built-in;
- SD Card slot;
- Voltage regulator: 5V 1A;
- 30.5mm X 30.5mm mounting holes;
This is a great first step on F7 flight controller, offering good features, the processor toke a big space on the PCB and we lost other features like 6 motor output to 4 motor output. The layout is not the best and the layout marks are only on the back of the flight controller which is not very good for the building process. Only Betaflight 3.2 supports the F7 processors. Overall this flight controller works very well and with this powerfull processor we can be asured that any software upgrade will work on this FC. At the moment Airbot released a newer version of this flight controller with the gyro soft mounted, should be a big improvement to this FC.
I want to thank to Airbot that made this review possible.
