Introduction: The module integrates high- accelerometers, gyroscopes, magnetometers, and barometers, and uses high-performance microprocessors and advanced filtering algorithms to quickly calculate the real-time attitude of the module. The module integrates high- accelerometers, gyroscopes, magnetometers, and barometers. Adopting advanced digital filtering technology can effectively reduce measurement noise and improve measurement accuracy The Z- heading angle is filtered and fused with a geomagnetic sensor, which solves the cumulative error caused by the drift of gyroscope integration in the 6- algorithm, long term stable output of heading angle data. Attention: Due to magnetic field detection, calibration is required before use, and it is necessary to from the magnetic field during use at least 20 centimeters away from hard magnetic objects such as interference areas, electronic devices, magnets, speakers, etc High performance 32-bit floating-point processor with a running frequency of up to 240MHz Based on Bluetooth BLE5.1 wireless transmission, the speed is faster and the transmission distance is longer, reaching up to 50m in open environments Support OTA Bluetooth wireless upgrade module firmware Default onboard antenna, with extremely low cost control and strong wireless signal under low-cost conditions Wide working voltage of 1.8V to 3.4V, typical value of 3.0V Color:As Shown Material:PCB Package Contents: 1 * Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
