The GY-86 features three 16 bit analog to digital converters (ADCs) for digitizing the gyroscope outputs and three 16 bit ADCs for digitizing the accelerometer outputs. For precision tracking of both fast and slow motions, the parts feature a user programmable gyroscope full scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user programmable accelerometer full scale range of ±2g, ±4g, ±8g, and ±16g.
DESCRIPTION :The MS561101BA is a high resolution altimeter sensors with SPI and I2C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 10 cm. The sensor module includes a high linearity pressure sensor and an ultra low power 24 bit ΔΣ ADC with internal factory calibrated coefficients.
HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry. The HMC5883L includes our state-of-the art, high-resolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation,and a 12-bit ADC that enables 1° to 2° compass heading accuracy.The I2C serial bus allows for easy interface.
Absolute Maximum Ratings :Stress above those listed as “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to the absolute maximum ratings conditions for extended periods may affect device reliability
FACTORY CALIBRATION:Every module is individually factory alibrated at two temperatures and two pressures. As a result, 6 coefficients necessary to compensate for process variations and temperature variations are calculated and stored in the 128-bit PROM of each module. These bits (partitioned into 6 coefficients) must be read by the microcontroller software and used in the program converting D1 and D2 into compensated pressure and temperature values.
