Everything from the 120MHz Cortex-M3 MCU to the three-axis accelerometer and the Bluetooth radio was on a single board.
This means a single analog input of the microcontroller is shared among all the input channels (except the 3-axis accelerometer).

By combining its three axis gyroscope with its three axis accelerometer, the newest iPhone is expected to reach a new level of sensitivity for apps.
It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

The orientation sensor automatically adjusts between portrait and landscape mode in most applications when the device is tilted, and the 2-Axis Accelerometer is great for controlling games that need simultaneous steering and acceleration.
Unlike almost all competitive products that use only one sensor to 'read' the body, BodyMedia's monitors incorporate temperature, heat flux, galvanic skin response and 3-axis accelerometer sensors to get accurate measurements of calorie burn, exercise intensity and sleep patterns that affect weight as well as health.

Examples include the FSM-SENS-1, a 6-axis sensor-only module that integrates with an external Freespace MotionEngine, and the FSM-SI-2, which combines the Freespace MotionEngine on an embedded microprocessor along with a 3-axis digital gyroscope, 3-axis digital accelerometer and optional 3-axis magnetometer (compass) to provide high-performance, calibrated motion data for a variety of applications.
The Oregon series has a built-in 3-axis electronic compass with accelerometer tilt compensation, which shows where users are heading even when they are standing still, or not holding it level.

The smartphone is designed for an optimal gaming experience with a six-axis sensor that fine tunes its accelerometer's ability to interpret simple movements of the device, so when the phone tilts up and down or left and right, the game can immediately respond in the same directions.
