Manual for Betaflight OSD Setup

Betaflight OSD (on-screen display) is integrated into BETAFPV F3 brushed flight controllers that show important flight data on your FPV monitors, such as battery voltage, current draw, and much more. On default, the OSD function is enabled and you could use the default configuration. Also, you could custom your own OSD menu. 

OSD with the AIO cameras

How would do an OSD with the AIO cameras? Which AIO cameras are supported with OSD function and how to connect the AIO camera to the FC? These are the issues we need to solute in this part. There is a video in and out on the FC itself, labeled CAM and VTX as show below. So as usual, all the AIO camera vtx could connect with the FC if you could separate the video in and out independently.

BETAFPV H02 is an AIO camera VTX with video out and in available. All you have to do is soldering the signal cable to the FC correctly.

For the camera VTX combo connected with cables, like FX806TC, just split the video cable ( yellow cable as usual) and soldering them to the FC correctly.

Other regular AIO cameras like VM275, FX805, Eachine XT02, etc, the video out and in signal is not available and you should do some modifications to it.

OSD Configuration

Enable the OSD function on the Configuration tab.

The OSD tab where you can configure the OSD settings.

Setting up Betaflight OSD is very simple, here are more details from the Oscarliang website.

Battery Voltage

As usual, the voltage value showing on OSD will drain about 0.6V when flying. Here is the conclusion about the battery voltage.

1) It is normal for a fully charged battery to show around 3.8V on OSD when throttle up. As shown in MMW's video, after 5s flying time, the voltage on OSD is 3.7V.

2) When the battery voltage is 3.7V, the OSD will show about 3.1V when flying.

3) The low battery alter show be no more than 3.1V. This is also the recommend value from MMW.

Below is a complete flying record with a fully charged battery by Benedikt from MMW. 

Minimalistic OSD Configuration for BetaFlight 3.2

The manual below is based on Benedikt's article.

BF 3.2 OSD has a huge list of features, but only a few are useful on micro FC with limited sensor support. To configure your OSD as above, you can copy the settings below and paste them into the CLI of your BetaFlight configurator, then enter "save" and enter.

- voltage
- flight time
- warnings
- crosshair
- "battery not full" alert: 4.1V
- "low battery" alert: 3.1V
- "battery critical" alert: 2.9V
- "flight time" alert: 2:00min
- "Clarity" font
