VR Brain 5 (PRO) vs VR Micro Brain vs Pixhawk

* Pro is only on request and customizable , the PRO IMU could be also based on Maxim , Analog Device and ST mems. * The two expansion bus support indipendent i2c , spi and some some specific I/O for manage multiple chipset. On expansion bus it's available also wifi module with specific nuttx driver. Ask for more info.

As request from some user i try to do a matrix comparison chart , if there are some error on Pixhawk help me to correct please :) 

After the VR micro Brain 5 here finally get the VR Brain 5.
Sorry for the long wait but we had to work a lot on the operating system, new driver and all the infrastructure to support the mission planner firmware repository.

Today the board is  available on the store.
Here are the first pictures of the oem version, I prefer to show you the board without enclosure because  it's a jewel of technology :)

It will initially be available in the basic version. Only for more experienced users that join our advanced dev program will be available version that supports up to 3 SPI IMU  with (Acc , Gyro , Magnetometer and barometer ) . In advanced configuration the board support until 2 VR Multiconstellation GPS Ublox 8  
Provides CAN Bus with driver on board, SD Card, and realtime operating system NuttX RTOS operating sysyem.

Roberto, can you describe the differences between the micro 5.1 and the VR Brain 5? Besides the size? 

What is the method for joining the dev team?

Comment by Roberto Navoni on August 14, 2014 at 12:49am


I'm preparing a Matrix compare table other user ask to me the difference : VR micro brain vs VR Brain vs Pixhawk.

For Join to the dev Team contact me in skype my account is virtualrobotix .

I'm Looking forward to the matrix.  I'd also like to see what power modules and other peripherals it connects with (current and voltage sense, telemetry, etc) ... I don't see a bunch of DF-13 connectors

Comment by FD on August 14, 2014 at 7:26pm

+1 please post the matrix here

Comment by mP1 on August 15, 2014 at 12:30am


Why has it only got 6 PWM inputs and not 8 ?

Comment by bocorps on August 15, 2014 at 6:36am

ya, please inform when matrix is ready. 

Also, do you sell a case for this board ?

Comment by Roberto Navoni on August 15, 2014 at 8:18am

@mP1 ,

on hardware available 8 PWM input as VR Brain 4.5 , on firmware in actual revision only 6 , we are working for implement also the other 2 channel . On SBUS and PPMSUM are available 8 channel or more .



Comment by Roberto Navoni on August 15, 2014 at 8:20am


the board is sell with Plastic enclosure. We are working to aluminium option It will be available in the next month. 


I'm working on matrix table : VRBrain 5 - VRuBrain 5 and Pixhawk. 

Comment by Suryana Putra on August 15, 2014 at 8:32am
Now I'm getting lost between VRBrain, Pixhawk and Dropix....all looks promising
Comment by James Betker on August 15, 2014 at 3:56pm

I'm actually looking for a control board for a small plane. Do you guys have any demonstrations of your boards working with Arduplane?
