VBrain Coming ... the ARM Cortex M4 revolution




Dear Friends,

after 2 month of test I'm happy to inform you that the VBrain is ready to fly.

The platform is a result of 4 years of work on ARM autopilot platform. It's last evolution of Multipilot32 platform. I'm very happy that this is the year of ARM and we are here to present our last creation : Simple , Smaller and Ready to Use.

VBrain is a good choose for OEM ready to use hardware platform.

The VBrainautopilot features include:

  • 168Mhz ARM CortexM4F microcontroller with DSP and floating-point hardware acceleration.
  • 1024KiB of flash memory, 192KiB of RAM.
  • MEMS accelerometer and gyro, magnetometer and barometric pressure sensor.
  • 8 RC Input standard PPM , PPMSUM , SBUS
  • 8 RC Output at 490 hz
  • 1 integrated high speed data flash for logging data
  • 1 Can bus 2 i2c Bus
  • 3 Serial port available  one for GPS 1 for serial option 1 for serial telemetry.
  • 3 digital switch (ULN2003).
  • Jtag support for onboard realtime debugger.
  • 1 Buzzer output.
  • 1 Input for control lipo voltage
  • Include in the standard Vbrain Package there is VBrain GPS module , the module support MTEK 3329 gps , Ublox module , Fastrak IT600. On the module is available optional magnetometer. You can disconnect the board and put it far from brushless motoros to solve the problem of noise on mag signal.
  • Physical Dimension 6x4 cm
  • Will be available a case


It's first Universal Arm hardware platform . On it is available different kind of firmware : Open or Closed source . The main firmware available is Arducopter32 , last revision is 2.7 In the next day will be available a full fly test.
This platform is fully compatible with different kind of RTOS : FreeRtos , ChibiOS , Nuttx , CooxOS .

Our first target when start to develop our hardware platform 2 years ago was to develop a simple and powerfull ide.

We develop VRIDE PRO that is a special distribution customize by FoxTeam and LaserLab guys. The Ide use Eclipse as Editor, GCC as compiler , GDB and OpenOcd as Debugger.

This is the link of ready to use Ide:

The ide support different kind of workspace and library. Our first target was porting all arduino and APM api to ARM platform.


The supported firmware are Arducopter32the last revision available is 2.7 the status of firmware is ready to fly .

The Workspace with last revision of code is available here :

Our Team are working also on PX4 enviroment , first target was to port Arducopter32 on PX4 and PX4 enviroment to Vbrain and MP32Fx platform.

The hardware is compatible also with other opensource firmware as AutoQuad AeroQuad and OpenPilot. A lot of work are doing on IDE and firmware to share it on our platform.
We try to work to a new Opensource Standard based on high performances STM32F4 micro controller.


The price for VBRAIN with GPS Board (MTEK 3329 rev) developer revision  is 199 euro.

It's also available a ready to use board with 3 days of support by team viewer at 270 euro.

There is also available a oem version of product.

We are Ready for pre order the first batch of production will be available in 3 weeks some sample is yet available.

Hi Ron,

at the moment the VBRAIN is available "only" in developer edition not yet in ready to fly .
It's possible also to have a ready to fly board only for beta tester don't for end user.

The firmware available is Arducopter32 rev 2.7.2 xx . So we are aligned in our porting at 98 % of code . Are you a developer or a end user ?

We think to close the test on stable revision of code for the middle of september.

The firmware is yet ready the hard work is check on air if all is ok .

The most advantages of new firmware is that all automatic functionality work fine :

stable mode , return to home  , auto navigation , ecc ecc

The comunication protocol is mavlink 1.0 . The price start from 199 euro to 270 euro your gps is supported in gps protocol and is possible to use it the magnetometer is yet integrated on board . What revision of gps do you have ? What is the brand  ?

And we are starting the integration test with "Pinguino" Project :)

Hi Roberto,

Is the Vbrain board available for purchase now? Is there a webpage? What options are there for GPS? Can I use my own GPS (uBlox Lea6) and still get magnetometer? Current price?

Sounds like a nice board.

Thanks in advance,

Hi Angelo,

the transceiver is not on board because our customer can decide to use the output as standard pwm output, i2c bus or can bus.



Comment by Angelo DP on August 27, 2012 at 12:25pm

The features list say there is a CAN interface. Is the transceiver already on board ? or must it be added on a daughter board ?

Hi Roberto,

Is it possible to use the DL1 led to indicate if there is a GPS fix?

Tested my new quad with VBRAIN today, and it worked great

No video toady :-(

Have a great weekend!

Try to decomment PPMSUM60 in config.h 



Comment by Oyvind Amundsen on August 23, 2012 at 9:35pm

Hi Roberto,


have altered the setting in APM_RC_MP32.cpp:








input_channel_ch7=0; //Altered from 14 to 0


But I still get no response from my radio (have tested 2 different FrSky RX modules)

Must I alter this in config.h ?

#define PPMSUM60

I do not use PPM SUM
