Use the NunChucky I2C Breakout Board Adapter to use your Wii Nunchuck controller in your own projects!
The DE-ACCM5G is an off the shelf 2 axis 5g accelerometer solution with analog outputs.
The DE-ACCM3D is the most advanced analog accelerometer solution to date, featuring a triple axis ±3g accelerometer chip.
The 6DOF Atomic is a XBee-ready, stripped-down Inertia Measurement Unit, designed to give good performance at an affordable price. So get measuring rotation and translation, people!
Need a tight and tidy way to measure 6-degrees of freedom? The SparkFun IMU Digital Combo Board, measures pitch, roll, yaw, and rate of acceleration on each axis in a very flat package!
Breakout board for the Analog Device ADXL345. The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16G.
The ADXL335 is a triple axis accelerometer with extremely low noise and power consumption - only 320uA!
The Sure Electronics 3-axis low-power accelerometer features only 10-bit (still good!) resolution, but the price is excellent!
You want to know where you are in space? The Pololu MinIMU-9 does it all - an L3G4200D 3-axis gyro and an LSM303DLM 3-axis accelerometer and 3-axis magnetometer onto a tiny 0.9″ × 0.6″ board.
