This is the first picture of VR BRAIN 4.5 + VR IMU GOLD.
Thi new imu expand the number of imu available for VRBrain .
With this addon is possible to have two active imu controlled by VR Brain.
On VR IMU Gold there are 3ACC 3GYRO 3 MAGN and a EEPROM for store temperature drift correction table.
With this kind of option we intend to improve a lot the quality of VRBrain for GOLD (Prosumer version ) and VRBrain PRO.
Now we are in development stages :) This is a good hack for your VR Brain 4.5 ;)
The main advantages for Arducopter32 rev 3.1rc3 is that with external IMU is more simple to have less problem with vibration , and is possible to put the magnetometer far , too electromagnetic fields.
This two option is very important to have a affordable and very high quality sensor data for your high speed cpu.
Is yet available in the code repository a branch that support external imu for your VRBrain 4.5
this is the link : https://code.google.com/p/vrbrain/source/browse/?name=ap_hal_ext_IMU
The imu is connected to SPI3 of VRBrain , but the onboard imu still available on other SPI1 so is possible to implement a code to read the two imu at same time to have more affordable data for your ahrs algorithm.
