F4 Brushed Flight Controller (DSMX Rx + OSD) [BF-]


Key Features
High performance CPU: STM32F411CEU6 CPU
Battery polarity reversed connection protection. The fc board remains perfect even if you plug the battery in wrong way.
Fully programmable through Betaflight, using the onboard USB port, tune all the parameters, PID's, and rates to your perfect settings
Designed to work with current Tiny Whoop or Blade Inductrix setups
Built in DSMX protocol native receiver (SBUS), compatible with almost ALL Spektrum radios(e.g. Spektrum DX6/DX6i/DX8...) or DSMX compatible transmitter module
The flight controller board comes pre-flashed with Betaflight firmware, and pre-soldered 55mm power cable pigtail with JST-PH 2.0 connector, AKA PowerWhoop connector.

BetaFlight OSD
Betaflight OSD (on screen display) is integrated in BETAFPV F4 brushed flight controllers that shows important flight data on your FPV feed, such as battery voltage, current draw and much more. You can even use it as a menu to change your quad’s PID, rates, filters and other settings.

How to do an OSD with the AIO cameras?

There is a video in and out on the fc itself, labeled CAM and VTX as show below. There should be a video in and out on the AIO camera, like BETAFPV H02 etc. If not, you would have to modify the camera for sure but it would totally be worth it. Here is an example.

BETAFPV H02 Camera, FX806TC, VM275, FX805, Eachine XT02 etc aio camera vtx are available to use the OSD function.

BETAFPV Support Freshdesk for BetaFlight OSD Setup.

Tips: There is no current sensor on the FC boards. So the amperage value on the OSD is invalid.

Binding Procedure

Step 1

Connet the receiver to FC and run the Betaflight. On Betaflight GUI, configure the UART1 port to serial port in Ports tab. Then click the Save and Reboot button in the lower right corner.

Step 2

In the Configuration tab, for Receiver Mode, choose Serial_based receiver (SPEKSAT, SBUS, SUMD); Serial Receiver Provider, choose SPEKTRUM2048. And click the Save and Reboot button in the lower right corner.

Step3
Type: set spektrum_sat_bind=9 in CLI and save.

Step 4
Repower the receiver. The orange light on the receiver will flash rapidly, which means it's on binding mode.

Step 5
Turn on the radio and select bind mode. Wait a moment. It means bind successfully if the orange light on receiver is solid on.

Status LED

This board has 3 LEDs to indicate the status, including Receiver LED ( Orange ), FC Status LED ( Red ) and FC Status LED ( Blue ). These three LEDs are all at the bottom of the FC board.


DSMX Receiver
Some pilots would complaint that it is definitely not a long range FC. It looses signal with my transmitter far too often and for what appears to be no reason. This issue is often caused by the location of the antenna. You should keep the antenna away from the FC board to get a stronger signal. For example, run the singal upwards. Thanks for Harley Finberg's advice.

This integrated DSMX receiver is NOT compatible with Spektrum DXe radio transmitter and OrangeRX RF module. For some Spektrum radio transmitter like DX6i/DX6e etc, the DSMX receiver may have a horrible range with your radio transmitter, please change the mode to DSM2 (DSMX in default). This issue is figured out by Micro Motor Warehouse.
