WTMotion WT901BLECL High-Precision 9-Axis Gyroscope+Angle Module - Bluetooth 5.0 & UART Interface

The module operates from 3.3V to 5.3V DC. This wide range allows direct compatibility with both 3.3V logic systems (like ESP32 or Raspberry Pi) and 5V systems (like standard Arduino boards) without requiring a level shifter.

The module supports two primary communication methods. For wired connection, use the UART TTL serial interface (TX, RX pins) with a configurable baud rate. For wireless connectivity, it features Bluetooth 5.0 Low Energy (BLE), allowing you to stream data to smartphones or computers using the manufacturer's app or custom BLE applications.

The static tilt angle measurement accuracy is 0.2°. The module uses sensor fusion combining the accelerometer, gyroscope, and magnetometer data with an onboard Kalman filter. This fusion, particularly the magnetometer-based heading correction, significantly reduces long-term gyroscope drift, maintaining accuracy during extended operation.

Yes, the output parameters are configurable via serial commands. You can set the data output rate up to 200Hz and select which data packets (e.g., quaternion, Euler angles, raw sensor data) are transmitted over both UART and Bluetooth interfaces.

The module is designed for PCB embedding. It features four gold-plated stamp holes (plated through-holes) at its corners for soldering directly onto a carrier PCB. This provides a robust mechanical and electrical connection, ideal for integrated designs in drones, robots, or portable devices.
