For RC Drone pilots, who need a high performance easy to use flight control system, BrainFPV RE1 (Racing Edition 1), is a flight controller that has a fully integrated graphical On-Screen-Display (OSD). Unlike any other flight controller, RE1's innovative design combines an OSD, a faster processor and the highest performance sensors all in one small package. Both dRonin and Betaflight are fully supported on RE1, allowing you to use your firmware of choice.



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 Mk.2).


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?


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.
