KAmodL3GD20

Opis

KAmodL3GD20 is a module with MEMS chip L3GD20 type. It allows to make measurement of angle velocity in range ±250 / ±500 / ±2000 angle per second. Module can be used for measurement of the object inclination and also as complement for magnetometer or accelerometer (e.g. KAmodLSM303) in precision measurement device of physical values. Communication with the module is realize by I2C or SPI interface.
