AIST-330 consists of 3 gyrochips AIST-120, 3-axis accelerometer ADXL-326, control and interface electronics and temperature stabilization system (option) The units is filled with drained gas. External connection: RSG-10 10-pin male connector (Russian type). The unit is also available without accelerometers as a 3-axis gyroscope with abbreviation AIST-330G.
