• WithRobot Biscuit Programmable WiFi 9-axis absolute orientation sensor

The Biscuit™ is an integrated module consisting of 3 dimensional motion sensor and Wi-Fi 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 Wi-Fi 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.

Warning: incorrect battery connection can damage the Biscuit™. If your battery has different outputs from the one shown on the above picture, please use the accompanied cable to switch the polarity. Compatible Battery Connector: Molex 51021-0200
