Thread: Brain FPV Flight Controller - Open Source (Tau Labs) Full-Graphic OSD

  1. #1

    Brain FPV Flight Controller - Open Source (Tau Labs) Full-Graphic OSD

    The Brain is a next-generation flight controller that is specifically designed for first person view (FPV) flying and includes a full-graphic on-screen display (OSD). The Brain is small and light (36mm x 36mm, 8 grams), so it is ideally suited for FPV mini quads but it can fly anything, from mini quads to large octo-copters and fixed-wing planes.

    The firmware running on the Brain is open source and based on Tau Labs, which gives you many exciting features and also a great cross-platform (Linux, Windows, OS-X) ground control software to configure your flight controller using USB. Importantly, open source firmware gives you complete freedom to do whatever you want with your flight controller; don't like the way the home arrow is displayed in the OSD? Improve the code and contribute it back for everyone to benefit. Naturally, this does not mean you have to be a programmer or know programming to use the Brain, but you are free to modify the code if you want.

    The final price and release data have not been determined, all we can say that the price will be very competitive and it should be available later this summer. We don't take preorders before the Brain is ready, but you can sign up HERE to be notified.

    The Brain is currently being tested by a number of experienced FPV pilots here on the lab on a number of different platforms (mini-quads, normal quads, tri-copters, planes). A video of a test flight and a complete list of features is below.

    FPV Specific Features:

    • Full-graphic OSD (360x266 for PAL), software adjustable black and white levels, PAL/NTSC autodetect
    • Audio output (not yet supported by software)
    • 3 analog inputs for voltage, current, RSSI measurement
    • RSSI measurement using PWM, PPM, or analog input

    Other Features:

    • CPU: STM32F405RG (32bit, 168MHz, 192kB RAM, 1MB Flash)
    • 64Mbit flash for settings, way points, logging
    • InvenSense MPU-9250 latest generation 3-axis gyro/accel/mag
    • Barometer: MeasSpec MS5611, ST LPS25H*
    • Receiver compatibility: PWM, PPM, S.Bus, DSM2, DSMX, HoTT SUMD/SUMH
    • Up to 10 PWM outputs
    • Up to 3 serial ports for telemetry, receiver connection, GPS, etc.
    • External I2C (e.g. for airspeed sensor)
    • CAN bus (needs external transceiver)
    • LEDs: 1x status (blue) 1x alarm (red)
    • Size: 36x36mm, weight: 8g

    * Final version will only include one type of barometer

    Update 2014/12/18: The Brain is now available, get it from here!

    reserved. Looking forward to getting a Brain
    If you are not trying to fit through an opening that is just too tight, you are not FPVing.

    looks very promising.... good luck!

    I think we'll see more and more flight controllers including the OSD as time goes on.
