About
The Seriously Pro Racing F3 NEO FPV Stack has Flight Controller (FC), Video Transmitter (VTX), On-Screen-Display
(OSD) and Power Distribution Board (PDB) features that makes it the system of choice for any new low-profile
multi-rotor build.
The NEO system comprises of two boards, a bottom board with the FC/PDB and a top board with an OSD and
VTX.
The Cleanflight OSD software is all new and supports a variety of features with more to come. The USB socket on
the FC allows configuration and firmware flashing via the cleanflight configurator. No additional software, other
than drivers, is needed.
The FC also has race timing transponder components. When purchased with a transponder LED and code it can
be used as a race transponder for lap/race timing.

OSD/VTX Board
• OSD with customisable layout.
• VTX with 0/25/200mw output.
• 40 Channels, with raceband.
• Button for changing VTX channel/band/RF power/power/etc.
• Configurable via cleanflight configurator, via the NEO USB socket.
• u.FL socket for antenna connection, gold plated.
• Display of amperage/current, voltage, RSSI, flight modes, on duration, armed duration, 5v, 12v, callsign, motors,
etc.
• Available without VTX module, so users can use external VTX or alternative compatible VTX modules.
• VTX can be turned off remotely (e.g via transmitter). Great for team races or in-pit configuration.
• Solder pads for 5V, 5V switched, 3.3V, 12V, Video IN/OUT, Audio, GND.
• Breakout 2.54mm pitch though-holes for connecting to UART1 on the NEO - e.g. for Bluetooth/Wifi modules.
• PicoBlade connector for no-solder connection to external VTX, with 12V/VIDEO/AUDIO/5V switched/GND
signals.
• 2.54mm Through hole pads for connecting Buzzer (controlled via NEO).
• 2.54mm Through hole pads for connecting 12V devices.
• Though hole pads for JST-ZH sockets (supplied) connecting CAMERA an EXTERNAL VTX boards.
• Solder pads for PCB side-mount antenna JACK connection (when not using u.FL connector).
• CAMERA and EXTERNAL VTX sockets power selectable between 5V and 12V.
• Hole for accessing the boot button (via paper-clip) on the NEO below it.
• Board is 36x36mm with standard 30.5mm mounting holes.
• 12 position connector for stacking above the NEO.
• Illuminating white LED.

Software
The SPRacingF3OSD/PDB runs the open-source Cleanflight OSD software which has an ever-growing community
of friendly developers and users. Being open-source means that you too can contribute to the system.
Cleanflight comes with a detailed manual that is reviewed and maintained by the Cleanflight developers and
community. No more out-of-date wiki pages and second-hand information.
See http://cleanflight.com for links to the manual. PDF copies can be downloaded from the github releases pages. Ensure you reference the manual that is appropriate to your firmware version.
History
The hardware was designed by the lead developer of Cleanflight to be the first brand-new open-source OSD system available to replace the ageing 8-bit MWOSD system and to pave the way for future OSD systems that build
on the Cleanflight codebase.
Failure to adhere to these warnings will void your warranty and destroy your hardware.
• Observe polarity at ALL TIMES. Check and DOUBLE CHECK before applying power. Do not rely on wire color-cod-
ing alone.
• Perform a continuity test between Battery + and Battery - terminals on the FC before powering up for the first time.
A short circuit can start a FIRE!
• POWER OFF before unplugging, plugging in or making any connections.
• Connect only 3S or 4S LiPo batteries to the FC/PDB. (4.2v per cell).
• Ensure the 3S/12V selection jumper is set correctly. If all three pads are bridged your board and attached equip-
ment will be destroyed - only connect the center pad SQUARE to a single TRIANGLE pad..
• Ensure the two 5V/12V selections jumpers are set correctly for your VTX and Camera. If all three pads are bridged
your board and attached equipment will be destroyed - only connect the center pad SQUARE to a single TRIANGLE
pad.
• Do not connect any other SOURCES of power to the NEO other than the a battery via the XT60/Battery pads and/
or a USB cable.
• Do not connect a LiPo to any where other than the XT60/Battery +/- pads.
• Do not connect GND, 5v, VIN, BATTERY+ or 3.3v to each other (short circuit).
• Do not connect GND, 5v, VIN, BATTERY+ or 3.3v to any inputs or outputs unless specifically stated.
• Do not connect any input or output to any other input or output unless specifically stated.
• Always align USB plug and socket when inserting/removing USB cables to prevent damage to the USB socket.
• Always use a current limiter when powering on for the first time - this can help save your equipment in case you
wired something incorrectly. (This applies to all builds, not just with this product!).
WARNINGS
GENERAL ADVICE
Follow the advice below for best performance and long-life of your product:
• Apply resin/glue to reinforce JST-SH connectors - helps if you crash your aircraft.
• To further protect the board from crashes you can add a some additional solder to the edges of the JST-SH and USB
sockets to reinforce them.
• Support JST connector sockets when inserting/removing cables.
• Ensure all wires are tinned correctly, make sure there are NO loose strands of multi-core cable sticking out - This is
VERY IMPORTANT FOR THE BATTERY CONNECTIONS.
• Ensure the board is the right way up when soldering the header pins and sockets. Once header pins or sockets are
installed they can only be removed by a soldering professional.
• For optimum performance do everything you can to prevent vibrations reaching the accelerometer/gyro sensor.
e.g. balance motors, props use rubber isolation grommets if required and secure everything - no loose cables/etc.
IMPORTANT:
• Use a high quality soldering iron and good solder.
• Tin/Lead solder is MUCH easier to use than other Lead-free solder.
• Use solder with flux and remove any flux residue after soldering. AVOID CORROSIVE FLUX!
• Check for and remove any solder balls that you may have created when soldering - use a magnifying glass.
• Ensure you have sufficient fume extraction when soldering.
• Pin headers that connect to the GND signal will be more difficult to solder because the PCB will sink the heat from
your soldering iron. Solder the other pins near to the GND pin first, then the GND pin - by the time you get to the
GND pins you will have heated the board and it will be easier to solder them.
• If you have never soldered before then DO NOT attempt to solder the OSD, practice on something else first. Get
some VeroBoard and some single-core wire from Maplin/RadioShack/etc and practive on that.
• Once you have soldered pin headers in place DO NOT attempt to remove them unless you are highly skilled in
de-soldering and have the correct tools. Overheating the board or components will destroy it.
