Brand new open-source OSD system. The stackable Seriously Pro Racing F3 OSD/PDB is packed with features to make the core of your multi-rotor system super tidy, wire free, lightweight and totally awesome! All-new firmware and all-new configuration software.

The Cleanflight OSD software is all new and supports a variety of features with more to come. The USB socket on the OSD allows configuration and firmware flashing via the cleanflight configurator. No additional software, other than drivers, is needed.

The OSD also has race timing transponder components. The LED that comes with an EVO can be used to allow the OSD to perform transponder duties thus allowing the switchable IR/LED STRIP on the EVO to be set to LED STRIP. 


The SPRacingF3OSD stacks with the SPRacingF3EVO, ACRO and DELUXE boards. There are just 8 simple stacking header plugs and sockets in each corner to connect, no mess of wires or pin headers sticking out everywhere.


The SPRacingF3OSD is designed with the future in mind. The source is open and anyone can contribute to making the system better. No-longer are developers tied to the old MinimOSD/MWOSD 8-bit code, the SPRacingF3OSD feature a 32-bit CPU with a floating-point unit. The PCB also features I2C socket, SWD socket, UART socket and solder pads for SPI and GPIO devices. What will you come up with?


The SPRacingF3OSD combined with an EVO/ACRO/DELUXE flight-controller is all you need for the core of your compact new multi-rotor build - just add Motors, ESCs and a receiver and you're done!

Customizable OSD Layout

Configure the elements on your OSD to your taste.

Next-Generation CPU

The SPRacingF3OSd has an ARM Cortex-M4 72Mhz CPU with Math co-processor (FPU) for a fast OSD system. No-longer are we stuck with old 8-bit ATMEL processors.

Configuration using Cleanflight Configurator

All-new configution section in the Cleanflight configurator allows you to customise any aspect of your OSD system.

5V and 12V BEC Power Supplies

High-current 5V and 12V power supplies for powering your FC, Receiver, LED Strip, VTX and other accessories.


USB socket for configuration of OSD.

No messing around with seperate FTDI adapters and no MWOSD software required!

LC Filter

Provides smoothed power to your FC, OSD and VTX. Isolates noise from your ESCs and motors.

Small and Lightweight

The SPRacingF3OSD has a standard 36x36mm form-factor with 30.5mm mounting holes on a premium 2oz 4 layer copper PCB for durability and maximum current handling.


The SPRacingF3EVO runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).

Current Sensor

Monitor your current draw and capacity used so you know when to land.

Helps extend the life of your batteries


The SPRacingF3OSD is a stackable design. Connect an FC above or below the board for a super-tidy and wire-free installation.

Stackable designs are proven to be more durable in a crash.

Battery and BEC Voltage Monitoring

Built in voltage monitoring for Battery, 5V and 12V supplies.

Developer Friendly

Developer friendly debugging port (SWD), unbrickable bootloader.
Open-source code available on GitHub.


Buzzer solder points to allow easy buzzer mounting.

I2C and UART Ports

I2C port, always powered.
UART port for additional connectivity.

Power Distribution Board

Integrated high-current capable PDB for Battery and ESC connections.

Cleanflight Logos

The SPRacingF3OSD features a copper-etched Cleanflight logo so you can show your support!



Flexible board design and robust and easy wiring. 

  • Practical - Keeps all your wires tidy.
  • Durable - Though-hole connectors for all main I/O for crash-proof installation.
  • Stackable - Mount to compatible FCs using just 2 through-hole pins from each corner.
  • Compact - Entire board measures just 36x36mm.
  • Professional - Symmetrical, Neat and Tidy.
