Asguard AIO
Asguard AIO

The Asguard flight controller is an OmnibusF4 with an integrated 4-in-1 ESC. This is a build guide showing how to build an Asguard based quadcopter.

The frame kit and the Asguard flight controller are from Airbot.

The motors I'm using are 1806, but you'll notice the ones in the photo above are orange and I've built the quad with black ones. This is because the wires on the orange ones are too short. 2204, 2205 or 2206 motors might be a better choice if you're planning on running 3 or 4 blade props or a higher voltage (4s or 5s) regularly.

I put an FrSky XM+ Receiver on the build first, but then switched to an X4R to test out S.Port telemetry.

The camera I'm using is a Sony Super HAD with the EFFIO chip. The VTX is a little 200mw 5.8ghz transmitter

Frame & Motors

Frame goes together like this. Use some thread lock!

I used 1806 Motors, but you should probably use some 2206 motors. Put the heat shrink on before you attach the motors.

Once you get the motors bolted on, warm the heat shrink to tighten it down

Wiring

Here's the pinout for the Asguard

Asguard Pinout

I soldered on a battery lead. I should have made this longer and routed it out the back for easier battery installation. There is even a little hook for the battery cable on the frame.

Next, I removed the micro jst connectors using my soldering station, but it's totally up to you if you want to use these.

Solder on your motor wires. Usually, when wiring ESCs 2 motors will be directly connected, e.g. no wires will be crossed, coming out of the motor into the ESC. Then the other two wires will have 1 set of wires crossed. For me, the wires between motors 1 and 4 had a cross between 2 wires and on motors 3 and 2 the wires were not crossed. You should just try wiring up one motor and seeing which way it spins by connecting a battery and connecting the flight controller to the configurator.

The smaller blue, white, red and black wires here are UART1, which we won't be using, but you could wire up if you need another UART for something.

Here's how you'll want to wire your receiver. White is the TX from the receiver and the RX on the flight controller, this wire will have the signal from your receiver into the flight controller. The green wire is the signal from the flight controller to the S.PORT input on your RX, if you have one.

This is what the other side of those connections look like, on the X4R

Now flip the Asguard over and wire up the video input and output. Yellow is the video signal and blue is ground.

The right side is the camera and the left is the VTX.

And add the wires for buzzer and LED strip.

The buzzer is the brown and red wires. The blue (V+), yellow (data signal) and white (GND) wires are for the LED strip.

Here's how the LED strip wiring looks:

And here's what it looks like attached:

OOooohh purple...

All wired up and it's nice and clean

If you want to use UART3, it's here:

FPV Gear

Plug in the VTX. I put some heatshrink around it as well.

Zip tie it down:

Zip tie down the RX too:

I used some extra 2mm x 5mm screws from the motors to bolt the camera to the carbon fiber plate. The holes were slightly too narrow, so I used a drill bit to drill the holes out about 1.5mm more each and it fit perfectly

Add some zip ties to attach the receiver antennas and use some heat shrink tube to attach them to the zip ties

Throw some props on there and we're done!

This is a really nice, clean build!

3D printed parts

3D printed parts for the LS frame or TC frame (they both use the same body style) you can get on Thingiverse here

Configuration

Here's my BetaFlight 3.2 configuration, which you can paste into the CLI in the configurator.

Be sure to test your fail safe (after removing your props) and to calibrate the ACC/GYRO.

Also note, the X4R is connected to UART6, which has a built-in inverter.

OSD

Upload a new font via the configurator if your OSD has some symbols displaying incorrectly:
