Here we are once again to bring you another cool product. Because on drone race every gram counts, we bring to you, one of the most recent flight controller All-In-One on the market, and when I say All-In-One I really mean ALL (flight controller, ESCs, PDB, OSD). Yes I’m talk about the Asgard another great/promising product from Airbot. This brand already accustomed us with great products like the FCs OMNIBUS, let’s see if this Asgard FC is at the same level has other products from this manufacturer.
In this subject I don’t have too much to say, the Asgard arrived to me inside of a very simple anti-static bag, without any kind of cables, just the flight controller as you see on the photos. So let’s talk about the his features.
First of all I want to tell you the features of this FC.
- F405 Processor;
- 4 x BLHELI_S 24A ESC;
- Built-in OSD;
- MicroSD reader for BlackBox;
- Built-in Current Sensor;
- 3 x UART;
- 5V 1A SBEC;
- Buzzer and LED Output;
All this high end features are what a pilot looks for about 14gr, light enough for all of this, the board makes our builds very very clean, just need to have the motor wires running the frame, wires for the receiver and that’s it.
Let’s start talking about the processor, this board features an ARM STM32F405 micro-processor, plenty of power to deal with all the data, Airbot provided us with the ability to use three UARTs (UART1, UART3 and UART6), but only the UART1 have inverter to plug our SBUS receiver. To provide gyro data, Airbot choosed the MPU6000 one of the most balanced gyros on the market, running at lower frequency, 8kHz against the 32kHz of the MPU6500, but because it runs at lower frequency makes him more immune to vibrations on the frame. This processor came flashed with BetaFlight v3.0.1 an old version, but we all know it’s upgradable so that’s ok. To update this flight controller we don’t have a button for boot, they only have available boot pads to solder as you can see on the photo below.
This board feature four ESCs with BLHALI_S firmware version J_H_15 DSHOT600 ready, this ESCs have the AM7520 MOSFET which at 25ºC they can provide 24A reducing this value with the increase of temperature, at 70ºC they reduce the current to 19A, so not bad for an All-In-One board. This ESCs provide a really smooth flight much due the proved BLHELI_S firmware.
One of the nicest features and something that I look for every time I choose a flight controller is the integrated OSD, controlled by the BetaFlight software, the pilot can change the settings of his quad with his radio and see through the goggles/monitor the changes. A really nice feature that help very much to tune the quad on the field.
How many of us already needed to record the flight log and only had 8MB free space to use? Now with this board, the pilot can record many flights for that just need to insert his own MicroSD on the reader and it’s ready to record.
Another great feature is the current sensor, a feature now (last months) adopted by almost every brand to feature their flagship flight controllers or PDBs, this allows to have a proper read of current that the quad is consuming. With this value we can have also the information of the power in Watts and everything can be showed on the OSD.
This board have three UARTs available the UART1, UART3 and UART6 but because this processor is a F405, the maufacturer need to had an external inverter for the SBUS protocol and it takes phisical space, so on this board, we only have one inverter located on UART1, if you will use SBUS protocol don’t forget to connect on UART1, otherwise your transmitter will not comunicate with the flight controller. The UART6 can provide two different voltage levels 3V or 5V, to choose you have to bridge the pads on the board.
This board also have two more plugs, one to connect the buzzer and LEDs, the other one to connect the camera and the video transmitter.
This board is absolute very well made, once in the hand I saw a really nice piece of technologie, good PCB quality, all the weldings very precise and clean. For all what this thing have inside it is really light and very compact. I already builded this board on a quad and the build is very very clean much less wires than before and reduced drastically the overall weight of the quad. The flights are pretty smooth, I really don’t miss anything this board has everything. During the build I felt that the soldering pads are really good, they have the right size not very large, but also not small and I think they will last.
But not even all is good, one of the things I thought “why they didn’t included?” was a pad with the battery voltage filtered, almost every video transmitter need at least 7V to work like Immersion Tramp, and the only place where I could get battery voltage was on the battery plug. I think that they shoulded include a VCC alongside with the VideoOutput. The other thing I would like to see on this board is the Boot button. My advise is to add a 470uF 35V capacitor at the main power input.
Overall this is a great All-In-One flight controller and I want to thank to Airbot that made this review possible.
