The module integrates high-precision accelerometers, gyroscopes, magnetometers, and barometers. It uses a high-performance 32-bit floating-point DSP processor running at up to 240 MHz and advanced digital filtering algorithms to reduce measurement noise and improve accuracy. The heading angle is calculated using sensor fusion, combining data from the geomagnetic sensor with gyroscope and accelerometer inputs to minimize drift and ensure stable long-term heading output. Calibration is required before first use due to magnetic field sensitivity. Keep the module at least 20 cm away from magnetic interference sources such as magnets, speakers, and electronic devices during operation. Wireless communication is supported via Bluetooth BLE 5.1, enabling reliable transmission up to 50 meters in open environments. Over-the-air (OTA) firmware updates are supported. The module features an onboard antenna and operates within a wide voltage range of 1.8 V to 3.4 V (typical: 3.0 V). Color: As shown Material: PCB Package Contents: 1 × Module
