Extreme Features

The SPRacing H7 EXTREME FPV Stack is a Flight Controller (FC) with DUAL SIMULTANEOUS GYROS, PID-Audio, On-Screen-Display (OSD), Power Distribution Board (PDB) and Video Transmitter (VTX), features that makes it the premium board of choice for any new low-profile multi-rotor build.

Extreme Flight Performance

A 400MHz H7 CPU and TWO GYROS working SIMULTANEOUSLY is simply unbeatable!

Ultra-fast H7 CPU

The SPRacingH7EXTREME has an ARM Cortex-M7 400MHz CPU with Math co-processor (FPU)

The H7 CPU is 2x as fast as F4/F7 CPUs which runs the control loop and filters at lightning speed.

Advanced IO support means zero jumpers and 7 flexible serial ports.

Simultaneous DUAL GYRO with a TWIST, literally!

With one Gyro at a 45 degree offset, the SPRacingH7EXTREME combines data from sensor 3 axes for every pitch/roll movement

e.g. full roll data from one gyro + 1/2 pitch and 1/2 roll data from the other gyro.

128MB Built-in QUAD SPI flash

The SPRacing H7 EXTREME has a QuadSPI 128MB ultra-fast flash chip.

Not only is the chip itself fast and huge, but it's connected using a 4-bit QuadSPI bus which means data transfers are 4x as fast!

Dual Dedicated SPI sensor connection

The two low-noise ICM20602 gyroscope and accelerometer sensors are each connected to the CPU on their own dedicated fast SPI bus.

Having each sensor on their own bus will allow data simultaneous transfers from the sensor to the CPU via DMA without the CPU having to wait!

MicroSD via SDIO 4-bit Bus

The SPRacing H7 EXTREME also features a MicroSD card socket for logging. Supports MicroSD/SDHC up to 32GB - just leave one in and log every flight!

The H7 EXTREME is the first Betaflight/Cleanflight to support the 4-bit SDIO bus, data transfers are 4x as fast as every FC before it.

The MicroSD socket is specially positioned so that the SD card is held in place by the USB connector so it cannot fall out, smart!

Boot, run and upgrade from SD card!

In another world first, the SPRacing H7 EXTREME is the first Betaflight/Cleanflight FC that allows firmware upgrades from the SD card.

It's also possible to boot from different firmware on SD card and store config on the SD card!

Microphone and PID-Audio

The SPRacing H7 EXTREME has CPU generated audio output and a microphone with an on-board audio mixer.

You can HEAR the PID controller working and you can hear your motors via the microphone.

Tune your aircraft by LISTENING and be one with your multi-rotor's performance.

BMP388 Barometer

The SPRacing H7 EXTREME has the latest BMP388 barometer for altitude related tasks.

It has higher precision and less drift over-time than previous sensors.

2-6S LiPo Support

The SPRacing H7 EXTREME supports direct connection to 2-6 cell LiPo batteries.

TVS protection diode fitted as standard.

Additional features

The SPRacingH7EXTREME has other great features now with upgraded performance and specifications.

RPM Filter & Bi-Direction DSHOT

Supports new Bi-directional DSHOT telemetry ESCs.

Bi-directional telemetry allows RPM filter in the firmware to remove motor noise for super smooth flight, no additional ESC telemetry wire needed!

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.

Multi-VTX support

The H7 EXTREME VTX board allows you to direct-solder either a TBS Unify or an RTC6705 module. The video transmitter can be even be turned off from your RC Transmitter!

Current Sensor

Monitor your current draw and capacity used so you know when to land or monitor motor efficiency.

Helps extend the life of your batteries, without one you're just guessing!

DSHOT and OneShot ESC support

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

DSHOT is pure-digital and electrical noise resistant.

PitMode / Team-Race-Ready

The SPRacing H7 EXTREME 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.

USB

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 6 serial ports.

Broad RC receiver support

Supports SBus, SumH, SumD, Spektrum1024/2048, XBus/IBus, PPM. 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.

Programmable LEDs

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

The SPRacing H7 EXTREME is allows you to use the transponder feature and the programmable LEDs at the same time!

PCB Cut-outs for battery wires

The H7 EXTREME PCB has cut-outs for battery wire connection that are easy to solder, strong and high-current capable.

Boot Button

The H7 EXTREME features a side-mount boot button to allow easy setting of boot mode for firmware flashing of the device.

Settings / VTX Button

The H7 EXTREME features a side-mount button to allow easy changing VTX settings - channel, band, RF-power, VTX ON/OFF and more!

Configurable

The SPRacing H7 EXTREME runs Cleanflight/Betaflight* firmware 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, un-brickable CPU bootloader.

Battery Monitoring

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

Buzzer

Buzzer port for audible warnings and notifications.

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.

5V BEC Power supply

2-6S capable with enough current for powering your FC, Receiver, LED Strip, VTX and other accessories.

Camera OSD control

The SPRacing H7 EXTREME allows control of your FPV camera's OSD via transmitter sticks on supported cameras

Low Profile

Measuring just 11.5mm high the H7EXTREME FPV stack is the smallest full-feature stack ever.

Fit it into even the tightest of air-frames or just make your life easier with all the room you'll have spare in a normal frame.

Built-in Power Distribution

The H7 EXTREME allows direct connection of ESC power cables - no external PDB is required. The power is transferred though a high-quality gold-plated 6-layer PCB with super-wide high-current PCB traces.

Designed by Mr Cleanflight!

The SP RacingH7EXTREME was designed and built by none-other than Dominic Clifton, aka Mr Cleanflight, the guy that created Cleanflight which spawned forks like Betaflight and iNAV.

How many other FC manufacturers have heritage like that?

Race Transponder *

The SPRacing H7 EXTREME 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.

  • 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!
