Secret picture from VR LAB : VR micro Brain 5.1 is coming ..... The micro drone revolution is started today :) The smaller and powerfull VRX platform available ever


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.

Our user like a lot the drone log because can doing check and understand better how the drone fly : best speed , best flip , rally ecc ecc ...

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 , AleBS , Skud85 and other great pilot :)


Some info and example are available on italian forum baronerosso :

It looks nice and compact hardware.

However, the APM seems to be not a good flight controller or software for small copters.

So, I have curiosity on special firmware for "Paramotor Drone".

Hi Jiro , 

yes the hardware is powerfull and compact based on our last revision of VRBrain . 

This is kind of Paraglider with motor where we put VRBrain .4.5 . We start from APM Plane and search right configuration for use with Paraglider . In actual revision it work fine when you are in air . The FWB , RTL , Loiter and auto mission work fine , but autolanding is hard .. so we are working to implement better control on Parachute when we are near land .... We are working with Ivan the CEO of MIM Paramodels that is a great expert engineer in Parachute design the best here in italy :)

Will this hardware be available for purchase?

Comment by Roberto Navoni on April 26, 2014 at 4:41am

Yes the hardware will be available for pre order in may . The official presentation of new Virtualrobotix Boards : VRBrain Micro 5.1 , VRBrain 5.1 , VR GPS and new Groundstation : VR Pad and Glass Station will be at Makefaire in california . The 17-18 may. I'll present it at this event and will be available in california for more info .

I love Skud85 style copter. I had no luck on 250 copter with APM.

Will "VRBrain 5.1" get CC3D position ?

Comment by Roberto Navoni on April 26, 2014 at 9:13am

Could be , the VRBrain is a lot more advanced of CC3D and support Openpilot firmware ,too i try some time it , but i prefer a lot APM Copter , some user that have CC3D use APM Copter derived by VRBrain version on their board and they are very happy of our firmware :)

are you an idea about the price of you great little board?

why you don t use black pcb board?(green is not beautiful lol)

Comment by criro1999 on April 26, 2014 at 8:31pm

Hi Roberto,

Would you please share your configuration (parameters) for APM for paraglider? 

Comment by Martin Szymanski on April 26, 2014 at 11:47pm

Neat. Back in my third grade science project in late 70s I made a cloud chamber. I made 3rd place. Sometimes teachers dont know. Even some of them told us Diesel Engines have higher RPM because of the high freq turbo sound. Amazing.

Comment by Roberto Navoni on April 27, 2014 at 12:21am


basically the parameter depend of kind of parachute that you use . When i start to test the Paraglider i use standard APM Plane , connect motor as a Plane and use 1 servo configuration for control the lenght of Paraglider aero brakes. I connect this servo to roll control ... Then start to check the PID and search the right setup ... is not so simple but is possible. What kind of paraglider are you using ?
