The SynergyF4 was designed as an upgrade to your standard F4 flight controller with a focus on cleaner and easier building. A TBS Unify Pro V3 or a Unify Nano can be directly mounted to the surface of the board with no tape or zip ties required. In addition, the FrSky XM+ and TBS Crossfire Nano can be directly mounted to the board for a quick and easy build process.
Solder bridge selectors on the bottom of the board allow for a wide range of components to be used with the FC.
Note: This FC is still compatible with any receiver and video transmitter. Simply connect the rx/vtx with wires to the correct pads.
Features
- Direct mounting for Unify Pro (5V) and Unify Nano (with adapter).
- Header holes for direct receiver installation.
- Built-in camera control via single wire (analog only)
- Built-in BetaflightOSD
- Buzzer: Dedicated pads for 5V (100mA max) buzzers.
- Onboard addressable LED.
- Built-in Tiny’s LEDs RealPit VTX power switch (selectable between ON-OFF-Remote)
- Receiver can be powered on via USB (VTX stays off)
- SmartAudio: Selectable between internal (FC controlled) and external (receiver).
- UART1: Receiver (FrSky, Spektrum, Crossfire, etc).
- UART3: SmartAudio (or any other desired output if SmartAudio is selected to pull signal from the “external” pad, designated RX SA on the top of the FC).
- UART6: ESC Telemetry (if applicable) or UART Cam control

SYNERGYF4 TARGET NOW LIVE WITH BF 3.5.7
SYNERGY SPECIFIC CHANGES from OmnibusF4 Target
Gyro:
- set align_gyro = CW0FLIP
- set align_acc = CW0FLIP
Camera Control (optional):
- resource CAMERA_CONTROL 1 A08
PinIO (optional, only if selected via the solder bridge):
- resource pinio 1 B15
- set pinio_box = 39
- set vtx_pit_mode_freq = 0
Pit mode “mode” selection in the modes tab will be used to control the vtx. The above CLI commands set the mode switch to control the pin output instead of sending a command to the VTX to go to the “graveyard” channel.
Before: Pit Mode - command VTX to go to its assigned graveyard channel via SmartAudio.
After: Pit Mode - controls the output of Pin B15 to output a “HIGH” or “LOW” command which controls the power that the VTX receives.
Revision History:
- Revision E
- The current production, first batch
- Revision F (now shipping)
- Added 22uF to the 5V supply.
- 0.1uF on 3V proc supply.
- Reverse protection diode on vbat.
- Boot button
- Added pinout silk on the bottom side of the board for the connector.
- 10k pull down for SmartAudio Lite (Unify Nano).
