The SPRacing F3/F4 NEO FPV Stack has Flight Controller (FC), Video Transmitter (VTX), On-Screen-Display (OSD) and Power Distribution Board (PDB) features that makes it the board of choice for any new low-profile multi-rotor build.

Jaw-Dropping Flight Performance

The SPRacing F3/F4 NEO uses advanced processor, sensor and software technologies to make your aircraft fly like it's on rails.
The SPRacing F3/F4 NEO flight-controller and the Cleanflight software enables the precision flying you need for fast FPV racing.

Low Profile

Measuring just 15mm high the NEO FPV stack allows for a low center of gravity and low profile frame which result in a quads with greater agility, control and speed than ever before.

It's no wonder frame designers world-wide are designing new frames to take advantage of the NEO FPV stack. Users of existing frames will find they are able to replace tall frame standoffs for much shorter ones.

25/200mW Video Transmitter (VTX)

The NEO OSD/VTX features a 40Channel 25/200mW video transmitter that can be even be turned of from your RC Transmitter!

5V and 12V BEC Power Supplies

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

OSD with customizable layout

Display VTX channel/band, battery voltage, current draw, capacity used, flight time, callsign, rssi, motors and other OSD elements.

Configure the elements on your OSD to your taste.

Current Sensor

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

Helps extend the life of your batteries

SPI sensor connection

The new low-noise ICM20602 gyroscope and accelerometer sensor is connected via a fast SPI bus. This enables the software to get more data even quicker to help stabilize your aircraft even better

DSHOT and OneShot ESC support

Full support for 4 DSHOT or OneShot ESCs for easy PID tuning and a sharper response.

DSHOT is pure-digital and electrical noise resistant

Next-Generation CPU

The SPRacingF3NEO has an ARM Cortex-M4 72Mhz CPU with Math co-processor (FPU) with 256KB Flash

The SPRacingF4NEO has an ARM Cortex-M4 168Mhz CPU with Math co-processor (FPU) with 1024KB Flash

Easy Installation

Solder as little as 4 wires per ESC. Use no-solder connections for camera and receiver with telemetry using larger JST-ZH and PicoBlade connectors (cables supplied).

XT60 socket can be soldered directly to the board for direct battery connection.


The SPRacing F3/F4 NEO is team-race-ready. If your team mate crashes-out on the track they can turn off their VTX remotely so you can fly on the same VTX channel.


Use the USB socket to configure the flight controller, OSD and also for pass-though configuration and flashing of BlHeli ESCs.

The USB socket is not shared with any of the 5 serial ports.

LC Filter

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


The SPRacing F3/F4 NEO features a MicroSD card socket for logging. Supports MicroSD/SDHC up to 32GB - just leave one in and log every flight!

Programmable LEDs

Output for multi-colored LED strips - great for FPV racing, line-of-sight flying orientation and night flying.

The SPRacing F3/F4 NEO is the first Cleanflight FC that allows you to use the transponder feature and the programmable LEDs at the same time!

Broad RC receiver support

Supports SBus, CrossFire, Spektrum1024/2048, XBus/IBus, SumH, SumD, FPort, PPM & more. No external inverters required (built-in), receiver powered via flight battery or USB for easy configuration.

Dedicated ports for PPM/SBus/SumH/etc for easy connections. Socket for plug and play Spektrum Satellite receiver.

Boot Button

The NEO features a boot button to allow easy setting of boot mode for firmware flashing of the device.

The VTX board even has a hole in the top to allow access to the boot button below it.

Telemetry support

Supports bi-directional and standard transmit-only telemetry systems including SmartPort/S.Port, HoTT, FrSky, Mavlink, IBus and LTM telemetry.

Telemetry enables audible and visible ground-station or receiver based alarms, warnings, information gathering and logging of FC data.


The SPRacing F3/F4 NEO runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).

Expansion Port

The always powered expansion port features I2C and 2 serial ports. It's perfect for GPS receivers, external sensors, ESC feedback or an always-on OLED Screen.

Developer Friendly

Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.

Battery Monitoring

Built in battery voltage monitoring, built-in current monitoring.


Buzzer port for audible warnings and notifications.

Settings Button

The SPRacing F3/F4 NEO OSD/VTX features a button for changing VTX channel, band, RF-power, VTX ON/OFF and more!

Cleanflight logos and stickers

The SPRacing F3/F4 NEO features a Cleanflight logos so you can show your support!

Each purchase direct from the Seriously Pro shop also comes with stickers! (when available)

Built-in Power Distribution

The NEO allows direct connection of ESC power cables - no external PDB is required. The power is transferred though a high-quality gold-plated 2oz copper 4-layer PCB with super-wide high-current PCB traces on all 4 layers.

GPS Ready *

Connect a GPS, Mag and Barometer via the expansion port for GPS Navigation
* Available in Cleanflight soon, New GPS features under active development in iNav.

Race Timing Transponder *

The SPRacing F3/F4 NEO features a race transponder system for recording your lap times. Each board comes with a special transponder code to identify you at race events. Compatible with i-LAP,aRCiTimer and Easy Race Lap Timer receiver systems.

* IR LED and i-LAP code available separately

World Drone Prix 2016 Track

Race Transponder *

The SPRacing F3/F4 NEO features a race transponder timing system. As you fly around the track the FC continually transmits your unique code via IR. As your aircraft passes the start/finish timing gate the track-side receiver records your lap-time.

* i-LAP Transponder code and IR-LED available separately. Works with i-Lap, EasyRaceLapTimer (ERLT) and aRCiTimer systems.

  • Compatible with professional high-speed iLAP receiver systems, as used by most racing clubs worldwide.
  • Also compatible with low-cost aRCiTimer and EasyRaceLapTimer for low-speed lap timing.
  • Connect a single IR-LED via flying lead.
  • Reduces your overall cost for a race-ready air-craft.
  • No fiddling around trying to fit transponders in a hurry on race-day. Just turn up at the race and have the race officials scan your transponder and you're ready!
