Dear Friends,

today we going in production with the first batch of micro brain 5.1 board. After see some micro drone based on vrbrain fly , we decide to support the development of this great platform ... so we start to develop a special revision of VRbrain 5  for this kind of products where the small dimension and low weight are very important factor.

This is fully total autonomous platform available for micro drone.

These are the specification : 

CPU STM32F4 VR OS based on NuttX kernel.

1 EEPROM or FRAM device for parameter storage. 


MSIC Barometer 10 cm resolution.  

8 PPM Radio RC Input .

8 PWM ESC - SERVO Output.

1 SBUS Radio Input compatible with Futaba SBUS and Spektrum ,too

1 SBUS Servo Output.

SD Card Reader 


2 LED Output 

1 Buzzer Output 

On board telemetry module availabe at 433 / 868 mhz. (option) 

connector for external VR GPS + MAGNETOMETER

dimension 4x4 .

native support of APM Firmware : 

APM Copter 

APM Plane

APM Rover 

Custom firmware available for boat and Paramotor Drone.

I think that special new mode ad hybrid loiter and drift are very interesting for these great toys :) 

some example of micro drone developed by Tommyleo and AleBS



Some info and example are available on italian forum baronerosso :

  • Hi Enrico no you have 8 wire for 8 channel .... PWM is accepted as default.

    The same of VRBrain 4.5

  • I read: "8 PPM Radio RC Input"; does this mean that to manage PWM radio inputs signal conversion will be needed?

    TNX, enrico

  • Looks great:)
    Any info about pricing and its older brother VR Brain5.0 ?

  • This is great news and perfect timing for my miniquad project :-)
