Description of product

Description:

The LSM303C is a 6 Degrees of Freedom (6DOF) inertial measurement unit (IMU) in a single package, specifically developed as an eCompass device. Due to the IC housing a 3-axis accelerometer and a 3-axis magnetometer combined with its low cost, the LSM303C was perfect for us to create this small breakout board. Each LSM303C Breakout has been designed to be super-flexible and can be configured specifically for many applications. The LSM303C Breakout can be configured to generate an interrupt signal for free-fall, motion detection and magnetic field detection.

The range of each sensor on the LSM303C is configurable: the accelerometer's scale can be set to ±2g, ±4g, ±6g, or ±8g, while the magnetometer has full-scale range of ±16 gauss, and supports I2C and SPI communication.

Each pin has been broken out on the LSM303C, with 10 plated through-hole connections featuring power and I2C and SPI functionality, interrupt outputs, and accelerometer and magnetometer data out. Please keep in mind that the LSM303C is a 2.5V device so supplying voltages greater than ~4.8V can permanently damage the IC. As long as your Arduino has a 3.3V supply output, you shouldn't need any extra level shifting.
