Gadgeteer Pigeon IMU


The Pigeon, by Cross the Road Electronics, is an IMU (Inertial Measurement Unit) designed with FIRST® Robotics Competition teams in mind. This lightweight device has 9 degrees of freedom, and contains an accelerometer, a gyro, and a 3-axis magnetometer. It can be connected to the Gadgeteer Port on the Talon SRX or HERO for power, or it can be wired to the CAN bus while powered from a separate 12V source. Use it during autonomous as an easy way to measure direction or acceleration in a direction!

Note: An additional procedure must be used to update pre 2017-image RIOs to support Pigeons. Instructions and examples can be found here.

  • 9 Degrees of freedom (3 Axis accelerator, 3 Axis Gyroscope, 3 Axis Magnetometer).
  • Full AHRS (Attitude and heading reference system): Yaw, Pitch, and Roll.
  • Gyro automatically re-biased after eight seconds of no-motion.
  • Optional Temperature Compensation for further reduced gyro drift and accelerometer error.
  • Boot Time: ~ 5 seconds
  • Optional Compass fusing for zero heading drift.
  • Data connection can be CAN bus, or Gadgeteer-data-cabled to Talon SRX (UART).
  • Connection strategy allows for multiple IMUs (multiple arm/manipulator servos, drivetrain heading).
  • Invensene MPU-9250 MotionTracking™ Device
  • Robot heading and Yaw are continuous, ideal for robot heading servos, and motion plotting. No need to modulo divide anything.
  • Talon SRX Motor controller and Pigeon have a direct line of communication (allows for advanced future motion profiled features).
  • Conformal-coated
  • Robot-level API implementation is simple, no exceptions and few error conditions to service.
  • Reverse Battery Protection
