FPV and OSD

Preamble

Thinking of adding video to your drone setup? Then you will need to immerse yourself into the first item, and possibly consider the second:

• First Person Video – FPV
• On Screen Display – OSD

Articles

• A simple getting started guide: FPV Starting guide and FPV System setup introduction
• A great article on choosing a FPV camera, Selecting a Camera for FPV.
• A great article on choosing an OSD system from Oscar Liang, Choose OSD for quadcopter | FPV data On Screen Display video
• For invaluable information on vieo transmitters for FPV, see FPV Video Transmitter buying guide
• For the MinimOSD there are two great guides Naze32, MicroMinimOSD and GPS | Turorial, which deals, primarily, with the firmware and Oscar Liang’s MinimOSD Micro Setup tutorial – Naze32 PID tuning via OSD menu, display RSSI voltage
• Complete FPV goggles guide – FatShark Skyzone – Drone Quadcopter Multirotor
• FPV – what NOT to buy !!! And what IS good, at any given time period.

Wiring Diagrams

There are many examples of wiring setups. Here is one for the EagleTree OSD Pro (source?)

Transmitters

Budget

At the lower end of the price range, there are generally three variations for the number of channels available (8, 32 or 40 and also 48) and various levels of power from between 25mW and 1000mW (1W) or higher. The most popular two levels of power are 200 mW and 600mW.

Obviously, the higher the power of your transmitter, the further the range of your signal. However, it is worth remembering that power is governed by the inverse square law, so if you double the power of your transmitter, you will only increase range by 1.41.

Antenna

The mushroom, or clover, leaf antennas are reputedly the superior antenna. They come in two distinct types, 3 and 4 blades. It is important to note that:

• 3-blade antenna is for transmitting;
• 4-blade antenna is for receiving

Transmitter Power Supply

Receiver

Most commonly there are 8, 32 and 40 channel receivers, and the newer 48 Channel. The main difference between the 32 and 40 channels, is that the eight additional racebands are included in the 40 channel version.

Confusingly the RC832 receiver comes in various forms which are able to receive 32, 40 or 48 channels and the case and labeling is usually identical. The only way of telling them apart is by cycling through the channels and counting them (see 1 and 2). The original receiver has a [what? – missing text]

The channels

5.8 GHz channels

The channels used by FatShark/ImmersionRC

“FatShark” frequencies

8 channel

Note that the 805 is not recommended, see Best Boscam RX?

They all internally use the same SkyRF RX5808 receiver module, but in 805 receiver the module placement is a big design mistake, using a too long PCB track that led to antenna coupling issues at those frequencies.
Also, the video output, on the same side as antenna is not the best placement, for ergonomics reasons.
The fancy LED channels display could be attractive, probably this is what catch your eyes, else I can’t explain the interest for this receiver, but not worth.

ImmersionRC

For a dual output, although most RC832 have dual output also, so one output can be viewed, while the other is recorded, try the ImmersionRC Uno5800 5.8GHz Receiver Race Edition UNO5800V4RE, £62.99. For second hand, they go for around £27.99 (i.e. ImmersionRC Uno 5.8GHz A/V Receiver).

The are a number of versions of the Uno, each supporting a different number of video channels. Number of channels supported:

• Version 1 and 2 – The standard ‘ImmersionRC/FatShark/Airwave’ 7 channels
• Version 4.0 – 7 + 25 channels = 32 channels
• Version 4.1 – 40 channels

From version 4 manual (Duo: (link), Duo 5800v4 Diversity Receiver Manual_en, and Uno: (link) Uno 5800v4 Receiver Manual_en)

The Uno5800v4 Alpha has a dual-personality. In stock form, it behaves as it’s predecessors, the v1, and v2. The standard ‘ImmersionRC/FatShark/Airwave’ 7 channels are supported… In its ‘unlocked’ mode, it adds an additional 25 channels…

From version 4.1 manual

ImmersionRC’s newest version (4.1) of their popular 5.8GHz receiver, the Uno 800 V4 now with 40ch This receiver includes the popular Fatshark/ImmersionRC ‘NexWaveRF’ series of A/V frequencies channels and now also includes an additional 24ch for 5.8GHz.

OSD

There are many types and brands, These can be used as standalone devices or in conjunction with a flight controller, or, indeed, can come built in to the flight controller. The BrainFPV is one such flight controller with built in OSD. There are hybrid devices which can be used as standalone or in conjunction with a flight controller.
