Description
KAmodLSM303 is a module with MEMS LSM303D type. Chip has a digital output (with using I2C or SPI interface) and allow to make a measurement of acceleration and magnetic field value in three axis. Thanks to programmable interrupt outputs, it is possible e.g. wake up a microcontroller after free fall detection or object movement. Module can be used in system with power supply 2.5 - 5.5V.
Basic features and parameters
- LMS303D chip (accelerometer and magnetometer) from STMicroelectronics
- Measurement range of accelerometer: ±2 / ±4 / ±6 / ±8 / ±16g
- Measurement range of magnetometer: ±2 / ±4 / ±8 / ±12 Gauss
- Power supply voltage: 2.5V - 5.5V
- Sleep mode / Low power mode
- Communication interface: SPI / I2C
- Embedded voltage regulator and logic level translator (SDA and SCL lines)
- Programmable interrupt generator (by free fall, movement detection or magnetic field detection)
- Place for soldering of pin header
- Mounting holes 3mm
- Module size (without connector): 27mm x 15mm x 3mm
