Pololu LSM6DSO – 3D акселерометър и жироскоп

Модулът е изграден с ST LSM6DSО – datasheet, който съчетава в един корпус 3-осов акселерометър и 3-осов жироскоп. Позволява избор от няколко работни режима – от ±2 до ±16 g за акселерометъра и от ±125°/s до ±2000°/s за жироскопа. Oтчитането на данните се осъществява по цифров интерфейс – I2C/I3C, SPI. Платката е с размери 13mm x 23mm, с монтажен отвор и с разстояние между изводите 2,54mm. Захранва се с напрежение 1,8V – 5,5V и има конвертор на логически нива на интерфейса.

Комплектът съдържа:

• Платка сензор – 1бр.

Характеристики:

• Размери: 13mm х 23mm
• Тегло без конектори: 0,6 г
• Захранващо/работно напрежение: 1,8V – 5,5V

Pinout:

PIN	Description
VDD	Regulated 3.3 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 1.8 V to 3.3 V input with VIN disconnected.)
VIN	This is the main 1.8 V to 5.5 V power supply connection. The SCL/SPC and SDA/SDI level shifters pull the I²C and SPI bus high bits up to this level.
GND	The ground (0 V) connection for your power supply. Your I²C or SPI control source (and any devices connected to the secondary interface) must also share a common ground with this board.
SDA/SDI/SDO	Level-shifted I²C/I3C data line and SPI data in line (also doubles as SDO in 3-wire mode): HIGH is VIN, LOW is 0 V
SCL/SPC	Level-shifted I²C/I3C/SPI clock line: HIGH is VIN, LOW is 0 V
SDO/SA0	SPI data out line in 4-wire mode: HIGH is VDD, LOW is 0 V. Also used as an input to determine I²C slave address (see below). This I/O is not level-shifted.
CS	SPI enable (chip select). Pulled up to VDD to enable I²C communication by default; drive low to begin SPI communication. This input is not level-shifted.
INT2/DEN	Programmable interrupt, a 3.3-V-logic-level output. Can also be used as a data enable trigger input or, in Mode 2, a sensor hub data ready input (MDRDY). This I/O is not level-shifted.
INT1	Programmable interrupt, a 3.3-V-logic-level output. This output is not level-shifted.
SDx	Mode 2: I²C master data line (MSDA) Mode 3/4: Auxiliary SPI data in line (SDI) (also doubles as auxiliary SDO in 3-wire mode) This I/O is not level-shifted.
SCx	Mode 2: I²C master clock line (MSCL) Mode 3/4: Auxiliary SPI clock line (SCK) This I/O is not level-shifted.
SDO_Aux	Mode 3/4: Auxiliary SPI data out line in 4-wire mode This output is not level-shifted.
OCS_Aux	Mode 3/4: Auxiliary SPI enable (chip select); pulled up by default. This input is not level-shifted.
