Availability: In Stock

 Assembled in the USA

We use only the highest quality components and a 6 layer circuit board for optimal signal integrity. RE1 is designed, assembled and tested using cutting-edge equipment by the best men and women in New England. *Lobster roll not included*

Faster Processor

The latest and fastest STM32 F4 processor, running at 180MHz, enables RE1 to run advanced flight control code with ease.

Better Sensors

The latest accelerometers and gyroscopes from Bosch Sensortec running at 1.6kHz give RE1 unparalleled flight performance.

Built for Racers

Participating in a race? We got you covered with RE1's integrated a multi-protocol (I-Lap, Trackmate) infrared (IR) transponder for lap timing. The transponder ID and protocol can quickly be changed in the field using the OSD menu. Race on!

Graphical OSD

BrainFPV RE1 has an integrated full-graphic On-Screen Display (OSD). Having the OSD in the flight controller also saves you from the hassle of using a separate OSD, so you can keep your build clean and simple. Our OSD is fully configurable using the dRonin or Betaflight configuration software and also includes a menu to easily change settings in the field.

This is not your old character-based OSD, it has advanced features, such as 3D support when used with a 3D camera (e.g. NerdCam3D Mk2) 

More Lights

We built dedicated hardware to control over 1000 programmable RGB LEDs. Crazy, we know. Use the OSD menu to easily change the LED color when racing.



Available accessory boards:

  • RE-1-Baro: Barometer add-on for RE1

More Options

Want to fly an octocopter? RE1 can control up to 8 motors. Want to attach accessories? Connect them using one of the two serial ports or the I2C port. Lost your drone? We added a dedicated buzzer port to help you find your drone when you crash (no worries, we've all been there). Sick of using external inverters for FrSky receivers and telemetry? No need for an external inverter here! RE1 has built-in inverters for both. Want more memory? We've included 128 Mbit of flash memory for settings and logging. What more could you want? A pony?

Open Source

RE1 runs either the dRonin flight stack or our own fork of Betaflight. The firmware does everything, including rendering the OSD. You can use either firmware depending on your personal preference and you can always switch between the two. dRonin has an advanced autotune feature that allows you to easily tune your PID gains for super stable flight and other advanced features, like navigation capabilities. Of course, it is also well suited for racing. Betaflight on the other hand is designed solely for racing and performs very well for that purpose.

***Change your VTX Channel & Power thru your OSD!

Support for “SmartAudio”, which allows other devices to configure the video transmitter through the audio cable. This technology is used in the TBS Core Pro OSD and the popular TBS Vendetta racing quadcopter, where the video transmitter channel and transmit power can be changed using the OSD menu.  This feature works with both the TBS Unify Pro 5.8G and the TBS Unify Pro 5.8G HV video transmitters.
