10DOF – GY-91 4-in-1 MPU-9250 and BMP280 Multi-Sensor Module

Description This tiny 10-DOF GY-91 sensor module is more compact than GY-80 module. The module uses combination of Single chip MPU-9250 with built-in 3 axis Gyro, 3axis Accelerometer, digital Compass and BMP280 improved barometric pressure sensor. The MPU-9250 is the company’s second generation 9-axis MotionTracking device for smartphones, tablets, wearable sensors, and other consumer markets. The MPU-9250, delivered in a 3x3x1mm QFN package, is the world’s smallest 9-axis MotionTracking device and incorporates the latest InvenSense design innovations, enabling dramatically reduced chip size and power consumption, while at the same time improving performance and cost. Improvements include supporting the accelerometer low power mode with as little as 6.4µA of and it provides improved compass data resolution of 16-bits (0.15 µT per LSB). The full scale measurement range of ±4800µT helps alleviate compass placement challenges on complex pcb’s Technical Specifications Model / Part Number: GY-91 Sensor Chips: MPU-9250 BMP280 Interface: standard IIC / SPI communications protocol Operating Voltage range: 3.0V – 5.0V (on-board low dropout regulator) Module size 14.3mm * 20.5mm (More compact than GY-80) Resolution: 16bit AD converter, 16-bit data output Gyroscopes range: ± 250, 500, 1000, 2000 ° / s Acceleration range: ± 2 ± 4 ± 8 ± 16g Field range: ± 4800uT Pressure range: 300-1100hPa Using Immersion Gold PCB, machine welding process to ensure quality 2.54mm pitch Pinouts VIN: Voltage Supply Pin 3V3: 3.3v Regulator output GND: 0V Power Supply SCL: I2C Clock / SPI Clock SDA: I2C Data or SPI Data Input SDO/SAO: SPI Data output / I2C Slave Address configuration pin NCS: Chip Select for SPI mode only for MPU-9250 CSB: Chip Select for BMP280 Applications Quad-copter or any embedded application requiring multiple sensors Robotic Arm stabilization 2 wheel drive and 4 wheel drive robots where platform stability is a concern Other Electronically Stable platforms Documents and Downloads MPU-9250 Datasheet BMP280 Datasheet What is Degrees of Freedom (DOF), see here BMP280 Arduino Library MPU9250 Library for Arduino MPU9250 Library for STM32 Package Includes 1x 10DOF – GY-91 4-in-1 MPU-9250 and BMP280 Multi-Sensor Module 1x 8 Pin Male Header Straight
