LSM6DS3TR-C + LIS3MDL 9DOF IMU - accelerometer, gyroscope and magnetometer I2C - Adafruit 5543

The sensor is based on the ST LSM6DS3TR-C system, a popular 6-DoF IMU accelerometer with a gyroscope. It allows you to measure acceleration (3-axis accelerometer) and spatial orientation (3-axis gyroscope). There is also a LIS3MDL 3-axis magnetometer on the board, which detects where the strongest magnetic force is coming from, usually used to detect magnetic north. The sensor can be supplied with the voltage of 3 V or 5 V , the same values assume the values of logical voltage. Adafruit 5543 uses I2C communication. It was equipped with the STEMMA QT / Qwiic connector, which makes prototyping much easier.

Presentation of the module prepared by the manufacturer .

Leads located on both sides of the board .

• VIN : Power pin (the board has a built-in voltage regulator, it should be powered with the same voltage as the logic level of the microcontroller used)
• 3Vo : 3.3 V output from the voltage regulator (load capacity up to 100 mA)
• GND : Ground (common for power and logic)
• SCL : The clock line of the I2C bus
• SDA : Data line of the I2C bus
• STEMMA QT : Connectors that allow the sensor to be connected to development boards with STEMMA QT connectors
• ADM : I2C address jumper of the magnetometer
• AGAD : I2C address jumper of the accelerometer
• INT1 : Primary interrupt pin (LSM6DS3TR-C chip)
• INT2 : Primary interrupt pin (LSM6DS3TR-C chip)
• INTM : Magnetometer Interrupt Pin (LIS3MDL Chip)
• DRDY : Data ready pin (when measurement data is available, pin shows low)

Detailed information on the module pins and address jumpers sensor can be found in the user manual prepared by Adafruit.
