Long time since my last post!
I'm glad to announce the new ArduIMU V3 that will take the place of the very successful ArduIMU v2 (flat version). We called it flat version because ArduIMU V2 was created in a time where 3 axis and even 2 axis gyros were not so common and we had to place some of the gyros vertically. Good times...
ArduIMU v2 was the first low cost IMU that had gyros that allowed me to keep it flat, but they were bulky and expensive. I had to use two gyro chips for the XYZ axis, another for the three axis acceleration and you had to place the magnetometer externally. Another "disadvantage" was that all the sensors (but the mag) were analog, by default limited to 10-bits and required all the analog inputs in order to read them and you were also limited by the default filtering configuration and other noisy issues.
All the limitation we had with ArduIMU V2 are all gone with the V3. ArduIMU V3 features the new MPU-6000, that includes 3 axis gyros & accells built-in and process everything internally that is some kind of dual core power (24-bits ADC sampling and sensor fusion is handled inside the MPU), the latest 3 axis I2C magnetometer HMC-5883L and the classic but very robust Arduino Atmega328 running at 16Mhz...
MPU-6000 uses SPI for max performance. Did I say user configurable low pass filtering and scale range? Hell yeah... and here are some of the other specs:
Other ArduIMU V3 features:
The release date is estimated to be in two-three weeks. We are waiting for the final big batch and finish some code. We will take pre-orders soon.
We also cooking BIG new goodies that will be announced also this month... =)
