Biscuit - Programmable WiFi 9-Axis Absolute Orientation Sensor [0282]


Biscuit as a WiFi Mouse

The Biscuit™ is an integrated module consisting of 3 dimensional motion sensor and WiFi communication module.

The 3 dimensional motion sensor includes Accelerometer, Gyroscope and Geomagnetic sensor. The Biscuit™ provides 3-axis absolute orientation in the format of Quaternion, Euler Angle or Rotation Vector as well as Linear Acceleration, Gravity, Heading and Temperature.

The WiFi module has an inherent micro controller unit (MCU) on which users can download their own programs developed on separate development environment (IDE).

The Biscuit™ can be operated using USB bus power or battery to be used as an independent device untethered to a host.
