UM7 Orientation Sensor

The UM7 is a 4th-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates. The UM7-LT is equivalent to the UM7, except that it does not include an enclosure and factory calibration is not available.


The UM7 also adds many new features, including higher gyro bias stability and lower noise, a new communication architecture for improved flexibility, optional NMEA packet transmission, UTC time-synchronization with external GPS, and support for third-order temperature compensation on all sensors. Connections for power and TTL serial communication can be made to the UM7 through a polarized five-pin male connector on one side, which mates with an included cable assembly. A pair of six-pin expansion headers on the other side of the board provide additional connectivity options, including an alternative SPI interface and a secondary serial interface that can be connected to an external GPS module

Quick Spec

  • Interface: TTL serial, SPI
  • Minimum Operating Voltage: 4V
  • Maximum Operating Voltage: 5.5V
  • Supported baud rates: 9600, 14400, 19200, 38400, 57600, 115200, 128000, 153600, 230400, 256000, 460800, 921600
  • Maximum Logic Voltage: 3.3V (The main UART pins, TX and RX, are 5V-tolerant and can be used directly with 5 V systems that are guaranteed to read 3.3 V as high. The secondary UART and some of the SPI pins are NOT 5V-tolerant.)
