***Change your VTX Channel & Power thru your OSD!
The Team Blacksheep (TBS) guys also got fed up with dip-switches and buttons, so they released video transmitters with 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.
However, until now, pilots who wanted to build their own custom racing drone had to resort to dip-switches and buttons, which feels like being in the stone age after having gotten used to configuring the video transmitter through the OSD menu with the TBS Vendetta.
Fortunately, the folks over at Team Blacksheep are awesome and sent us the specifications for their “SmartAudio” standard, so we could add it to the BrainFPV RE1 OSD. A few sessions of coding later, we added the “VTXConfig” module to dRonin (see GitHub pull-request). This feature works with both the “TBS UNIFY PRO 5G8” and the “TBS UNIFY PRO 5G8 HV” video transmitters.
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).
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*
The latest and fastest STM32 F4 processor, running at 180MHz, enables RE1 to run advanced flight control code with ease.
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!
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.
RE1 stacks directly on top of the Mini Power Board (mPB) !!WITHOUT ANY WIRING!! to give you accurate current and voltage sensing as well as clean power for all your gear. Doesn't get much better. Or sexier.
Brilliantly designed with extendability in mind. Future accessory boards can be stacked on top of RE1, connecting to it using high speed interfaces without the fuss of wires. Yeah, we think ahead.
Available accessory boards:
- RE1-Baro: Barometer add-on for RE1
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.
