Type-P Inertial Family
Smallest and smartest SMD IMU & AHRS Models
OPUS-Inertial-P20 devices combine 3D accelerometer, gyroscope and magnetometer and they are specifically designed for low powered applications demanding precise inertial measurement and attitude information thanks to our proprietary EKF engine.
P20 model is 10x10 mm with 50mW consumption. P20 model is 12.1x12.1 mm with 80mW consumption. With only these sizes and power consumption, they are ideal for miniature or battery powered systems. I2C, UART and SPI interfaces are independently supported so that devices can reach 1kHz raw or processed output. They have the easiet firmware for device access and control.
