The LSM6DS33 combines a digital 3-axis accelerometer and 3-axis gyroscope into a single package. The sensor provides six independent acceleration and rotation rate readings whose sensitivities can be set in the ranges of ±2 g to ±16 g and ±125°/s to ±2000°/s, available through I²C and SPI interfaces. This LSM6DS33 carrier board includes a 3.3 V voltage regulator and integrated level shifters that allow operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
The LSM6DS33 inertial measurement unit (IMU) has many configurable options, including dynamically selectable sensitivities for the accelerometer and gyro, a choice of output data rates, and two independently-programmable external inertial interrupt pins. The accelerometer and gyro can be individually turned on and off to save power. The sensor can be configured and its readings can be accessed through a digital interface, which can be configured to operate in either I²C (TWI) or SPI mode.
The carrier board includes a low-dropout linear voltage regulator that provides the 3.3 V required by the LSM6DS33, which allows the sensor to be powered from a 2.5-5.5 V supply. The regulator output is available on the VDD pin and can supply almost 150 mA to external devices. The breakout board also includes a circuit that shifts the I²C clock and data lines to the same logic voltage level as the supplied VIN, making it simple to interface the board with 5 V systems, and the board’s 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
