$0.00

3-axis Inertial Measurement Unit (IMU) + 3-axis Digital Compass

Stage: Production

Available on backorder

Description

H0BR4x is a 3-axis inertial measurement unit (IMU) combined with a 3-axis digital compass module based on STM32G0 MCU, LSM6DS3TR-C IMU and LSM303AGRTR compass.

  • 2 x 3-axis accelerometers for inertial force and gravity vector measurements.
  • 3-axis gyroscope for angular rate measurements.
  • 3-axis magnetometer for measuring magnetic inclination and orientation.
  • Digital temperature sensor to provide temperature measurements and calibrate gyroscope temperature drift.
  • Use H0BR4x as an integrated IMU for attitude estimation in drones and other robotic platforms.
  • Use as inertial-/gesture-based input device.
  • Supports sample readings of all sensors to an internal SRAM buffer, the CLI output or to a port in a remote module.
  • Supports streaming of any sensor data to an internal SRAM buffer, the CLI output or to a port in a remote module. Streaming duration and period (sampling frequency) can be adjusted.
  • Connect to external hardware or combine with other Hexabitz modules!
