Product description: LSM303C - 3-axis accelerometer and magnetometer IMU 6DoF I2C/SPI - SparkFun module.
The MEMS module allows the measurement of acceleration and magnetic field in three axes of three-dimensional space. The device is a combination of a digital accelerometer and magnetometer, communicating via the SPI or I2C bus. In addition, it has a built-in temperature sensor, an integrated FIFO buffer and programmable interrupts, which allow, among other things, for free fall detection.
For communication with the central unit, the user can select the SPI or I2C interface. The module has the necessary passive elements for proper operation of the system. The leads are holes to solder thegoldpin connectors(not included in the set), which allow the sensor to be connected bywires ordirectly connected to the contact plate.
LSM303C module specification
- Operating voltage: 1.9 V to 3.6 V
- Communication interface: I2C or SPI
- Accelerometer:
- 3 axes: X, Y, Z
- Adjustable range: ± 2 g, ± 4 g, ± 8 g
- Resolution: 16 bits
- Magnetometer (compass)
- 3 axes: X, Y, Z
- Scope: 16 gauss
- Resolution: 13 bits
- Outlets: holes for goldpin connectors - 2.54 mm raster
- Built-in temperature sensor and FIFO queue
- Programmable interruptions that allow, among other things, free fall detection
- The jumpers enable disconnection of the I2C bus line pull-up resistors
- Plate dimensions: 26 x 25 mm
- Three mounting holes with diameter: 3 mm
Details on the technical parameters of the sensors can be found in the documentation.
Since the maximum voltage with which the system operates is 3.3 V, a voltage converter is required to work with Arduino. The exception are modules working with 3.3V e.g. ArduinoPro Mini 328 - 3.3V/8MHz.
