Fermion - 3-axis magnetometer - BMM150 - I2C/SPI - DFRobot SEN0419

Module with a three-axis magnetometer from DFRobot , equipped with a Bosch BMM150 system - based on the FlipCore technology. It enables the measurement of the magnetic field in the range of ± 1300 uT (X and Y axis) and ± 2500 uT (Z axis) with a measurement resolution of 0.3 uT . The module provides information about absolute orientation with high accuracy and precision of measurements.

The most common questions are: what is a magnetometer? What is a magnetometer for? The answers to these questions (and more) can be found on our blog in the article Magnetometr - how does it work and what is it for?

• Intelligence drones
• Recreational drones
• Indoor and outdoor navigation in open spaces
• Collecting information about the magnetic course
• Augmented Reality
• Tilt-compensated electronic compass for map rotation
• Magnetometer in the phone

The module has outputs in the form of solder pads to which the goldpin strip included in the set should be soldered. Each lead has been described, which makes the connection much easier.

• VCC - power pin
• GND - the ground of the system
• SCK - clock line of the I2C / SPI interface
• SDI - data line of the I2C / SPI interface (input)
• SDO - data line of the SPI interface (output)
• CS - Chip Select
• PS - selection of the communication protocol
• DRDY - ready to receive / transmit data
• INT - interrupt pin
