Product Description
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.
This board is a compact (0.4" x 0.9") breakout board for ST’s LSM6DS33 inertial module, which features a 3-axis digital linear accelerometer and 3-axis digital rate gyroscope; we therefore recommend careful reading of the LSM6DS33 datasheet (1MB pdf) before using this product. The LSM6DS33 is a great IC, but its small package makes it difficult for the typical student or hobbyist to use. It also operates at voltages below 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V. This carrier board addresses these issues by incorporating additional electronics, including a 3.3 V voltage regulator and level-shifting circuits, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LSM6DS33, as shown in the product picture.

Included components
A 1x9 strip of 0.1″ header pins and a 1x9 strip of 0.1″ right-angle header pins are included, as shown in the picture. You can solder the header strip of your choice to the board for use with custom cables or solderless breadboards, or you can solder wires directly to the board itself for more compact installations.
