What’s Special about the Micro Swift 3 FPV Camera?

Note that the camera I received is just a prototype, the image quality isn’t finalized so I am not going to test it just yet, but there are some very interesting new features I want to show you right now.

Why Replacing OSD Pin with UART?

The GND and OSD pins have been replaced by TX and RX pins on the Micro Swift 3.

This allows you to connect the camera directly to the flight controller for camera control without any additional resistor or capacitor.

There are benefits and downsides to this solution however:


  • More reliable performance and easier to setup, it doesn’t require any additional resistor or capacitor to work
  • More versatile as it allows more complicated commands and data, such as “long press” to change scene, which wasn’t possible before with the PWM signal via the OSD pin


  • You can only change camera settings on the Micro Swift 3 using a flight controller, you can’t use a joystick anymore

Spec & Unboxing

  • Input Voltage: 5V – 36V
  • IR Blocked
  • NTSC / PAL optional
  • 2.1mm lens
  • Weight: 6.2g
  • Supports On-Screen-Display (OSD) to display timer, battery voltage, etc

The Micro Swift 3 camera includes a silicone wire harness, a metal mounting bracket, and various screws and spacers. It doesn’t come with the little joystick since it’s no longer needed.

The mounting screw holes on the camera are metal inserts.

Just like the Micro Eagle, the lens/housing is fixed in place on the PCB with epoxy glue rather than screws like the Micro Swift 2.

Comparing to the previous Micro Swift 2, the latest version appears to be exactly the same size, but I noticed that the PCB has been redesigned.

Runcam also told me that they might use a standard M12 size lens on the tiny Micro Swift 3, similar to what they did in the Micro Eagle. Larger lens generally means better image quality, but a few grams heavier.

A closer look at the back of the camera.

Image Quality Testing

I will test the Micro Swift 3 soon when the production version comes out.

    How is the durability? I destroyed the case of my micro Swift several times, is it still possible somehow to change the case?
