Mpu9150 9 Axis Attitude Gyro Accelerator Magnetometer Sensor Module

Rs. 133.00 Rs. 153.00

MPU9250 nine-Axis Attitude Gyro Accelerator Magnetometer Sensor Module features the MPU-9250, which is a multi-chip module (MCM) which include two dies integrated into a single QFN bundle. One die houses the 3-Axis gyroscope and the 3-Axis accelerometer. The other die houses the AK8963 3-Axis magnetometer. Hence, the MPU-9250 is a nine-axis Motion Tracking tool that mixes a 3-axis gyroscope, three-axis accelerometer, 3-axis magnetometer, and a Digital Motion Processor (DMP). It is primarily based on I2C Address, Address: 0x68 by means of default, 0x69 if AD0 is pulled high.

The MPU-9250 additionally features an embedded temperature sensor. This module includes pull-up resistors at the SDA, SCL, and nCS strains, pull-down resistors on the FSYNC and AD0 strains, and an on-board three.3V voltage regulator permitting you to energy the module from 5V resources inclusive of an Arduino. If you desire to power the module from three.3V you may bridge the solder jumper next to the voltage regulator to skip the regulator.
Features :
1. Acceleration, Gyroscope, and Magnetometer
2. 9 DOF module
3. Build-in ultra-low noise linear LDO voltage regulator.
4. Built-in onboard filters, which reduce noise from the motor and other high current electronics.
5. All sensors connected to the I2C bus.
6. Build-in the Logic level converter for I2C.
7. Power indicator LED.
8. Using Immersion Gold PCB, machine welding process to ensure quality.
9. On-board pull-up resistors on SDA, SCL, and nCS
10. On-board pull-down resistors on FSYNC and AD0
