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
