Why "+" in the name? Because it's an Inertial Measure Unit (sensors and hardware filter circuitry) plus an Arduino-compatible processor that can run our Attitude Heading Reference System (AHRS) code, based on Bill Premerlani's DCM algorithm. This hardware consists of a 3 axis accelerometer and three gyro sensors, dual power regulator (3.3v and 5v), GPS port, an Atmega328@16mhz and a lot of status LED's. It's the cheapest IMU-AHRS on the market! (If the product is out of stock here you can also buy it for the same price at
Sparkfun)
Note 1: This IMU can serve as a replacement for ArduPilot's thermopile sensors with the 2.51 code and above.
Note 2: This IMU improves upon the first release in that the high-pass filter, which was reducing the effeciency of the DCM code, has been removed.
Note 3: As of March 11th 2011, all of the ArduIMU pcb boards will be green instead of blue. Everything remains the same, in terms of functionality. This is only a physical change, so don't worry if your IMU is green; you didn't get a prototype or anything of that sort, you just got the newest fully functional production batch!
