The new and flat version is now available for pre-order for just $129, the estimated shipping date should be Tuesday and you can get it here. I also have big discounts for dealers and high quantity orders.
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!Note: this IMU is not designed to work with ArduPilot as is, and is not a replacement for ArduPilot's thermopile sensors. We may in the future release versions that do work with ArduPilot, but this version is designed as a stand-alone IMU/AHRS, for use with your own projects.Includes the pin headers and all the sensors needed, some assembly is required.Features:-Flat Desing.-Low cost.-3 Axis Accelerometer.-3 Axis Gyroscope-Arduino Compatible.-Source Code included and Open Source!-Power LED (Green).-Status LEDs (Red, Blue, Yellow).-1 SPI port.-1 I2C port (possible expansion shield with magnetometers).-Two PWM outputs (for servos).-GPS port (uBlox ready!).-Protection diode.-Serial port output with servo standard connector for easy interface with any device (Ground, 5V, TX-OUT).-Latest Firmware-Board-Schematics-XY gyro LPR530AL-Z gyro LY530ALH-XYZ 3g Accel.

Automatik: yes, we did discuss this with Sparkfun and may release related products with them in the future, such as a version with a magnetometer for indoors use. The code, which Jordi developed with Bill Premerlani, is the real differentiating factor. We think many people will prefer an all-in-one "black box" solution with sensors and processor on the same board, which is what ArduIMU+ offers.
Looks nice !
Looking at schematics it looks exactly like Sparkfun's Razor 6DOF board + Arduino chip and GPS connector.
Sparkfuns's schematic here and ArduIMU schematic here. Same accel and gyros including filtering arrangement. Only difference I see is that gyros HP pin does not have 10k pull down resistor, and that gyro PD and ST signals are not available are tied directly to ground. Which leads me to think that gyro output will have same "characteristics as described in the Razor thread
