WitMotion WT901 AHRS MPU9250 9-axis Accelerometer, 3-axis Eletronic Gyroscope+Acceleration+Angle+Magnetometer, TTL Data Outout
Description
-WT901 series module integrates high-precision gyroscopes, accelerometer, geomagnetic sensor, high-performance microprocessors and advanced dynamics solves dynamic Kalman filter algorithm to quickly solve the current real-time movement of the module attitude .
-The use of advanced digital filtering technology, can effectively reduce the measurement noise and improve measurement accuracy.
-Integrates gesture solver, with dynamic Kalman filter algorithm, can get the accurate attitude in dynamic environment, attitude measurement precision is up to 0.05 degrees with high stability, performance is even better than some professional Inclinometer!
-Integrate voltage stabilization circuit, working voltage is 3.3v ~ 5v, pin level compatible 3.3V and 5V embedded system .
-Supports serial port and IIC interfaces. Serial port rate is adjustable from 2400bps ~ 921600 bps , IIC interface supports full 400K rate.
-Highest 200Hz output data rate. The output data and rate can be adjusted.
-The 4-way expansion ports can configured as analog input, digital input, digital output, PWM output function.
-With GPS connectivity. Acceptable in line with NMEA-0183 standard serial GPS data form GPS-IMU navigation unit.
-Stamp hole gold plating PCB design, can be embedded in the user’s PCB board.
-4layer PCB technology, thinner, smaller, and more reliable.
