BetaflightF3 Flight Controller


The flight controller designed to use every possible feature of Betaflight. FPVModel has worked over the last year with Boris B to develop the features and design aspects needed/wanted by betaflight users. Its a true a game changer. Why? With the SmartAudio interface to a TBS Unify VTx (or IMRC Tramp) the Betaflight OSD allows everything to be controlled by stick command at the field, including changing VTx channels and power. Also, say goodbye to separate PDBs, OSDs and endless stacking. Say hello to perfect synergy with Unify VTx and Betaflight control!

This board features a 3A power draw giving users extra room for added attachments through uart ports. The six layer PCB is a more expensive design approach but was needed to give the ability to have a PDB that was capable of having wiring pads on both the top and bottom of the board. By using the six layer design we were able to increase the size of the pads and work around all the components all the while giving esc connections in the corners of the board rather than bunching all connections on either the top OR the bottom.

Featuring a fully functioning OSD that can be configured in Betaflight this board will make configuring your OSD a breeze. Supports TBS SmartAudio functionality, you can change settings on your FPV video transmitter EASILY. Using the Betaflight OSD, you can change channel or transmit power setting on your TBS Unify or ImmersionRC Tramp video transmitter, without ever touching your copter!

The team at betaflight have been hard at work developing DSHOT and this board is also compatible with the latest release. But we didn’t stop there, this board also features a micro adapter to accept TF cards for those of you that like to follow up your flights with reviewing black box logging...we think we know of at least one guy that will like that. 


    And, of course, the BetaflightF3 flight controller runs on the open source Boris B. Betaflight firmware. The hex file target is "BETAFLIGHTF3".

    Choosing your power supply for video is relatively simple. Betaflight FC has two options, 5v and battery voltage. Choose your camera voltage by jumping either the 5V solder section or the Vbat solder section. (its recommended to use Vbat, Most cameras and Video transmitters can run off battery voltage) If using 5v it is recommeded to only power your camera and get the power for Vtx from another source.

    Please note that the SBUS / DSM2 receiver pin is the UART 2 of this board. So setup that way in Betaflight Configurator. Also, note you cannot use the separate UART 2 tx/rx pins for anything else if you're already using the SBUS/ DSM2 receiver pin.


    Failure to adhere to these warnings will void your warranty and destroy your flight controller.

    • Observe polarity at all times. Double check all connections before applying power.
    • After double checking all connections its a good idea to triple check connections...positive to positive, negative to negative. 
    • Make certain all channel inputs match corresponding outputs or else undesired flight characteristics will happen. 
    • Keep magnets away from flight controller.
