The LIS3MDLTR has 16 pins, and each pin has a specific function. Below is the description of each pin:
Pin Pin Name Function Description 1 VDD (Pin 1) Power supply pin. Connect to the positive supply voltage (typically 2.16V to 3.6V). 2 GND (Pin 2) Ground pin. Connect to the system ground. 3 SCL (Pin 3) Serial Clock Line for I2C communication. Connect to the I2C clock line of the system. 4 SDA (Pin 4) Serial Data Line for I2C communication. Connect to the I2C data line of the system. 5 ADDR (Pin 5) I2C address selection pin. Configures the I2C address of the device. 6 N/C (Pin 6) No Connection pin. Not used in the circuit, can be left floating. 7 DRDY (Pin 7) Data Ready pin. Goes low when new data is available for reading. 8 INT1 (Pin 8) Interrupt pin 1. Used to signal an interrupt to the host system. 9 INT2 (Pin 9) Interrupt pin 2. Used to signal another interrupt to the host system. 10 SA0 (Pin 10) I2C address selection pin. Used to choose between two possible I2C addresses. 11 N/C (Pin 11) No Connection pin. Not used in the circuit, can be left floating. 12 VDDIO (Pin 12) I/O voltage supply pin. Connect to the voltage supply for the I2C interface . 13 VDDIO (Pin 13) I/O voltage supply pin (same as Pin 12). Connect to the voltage supply for the I2C interface. 14 N/C (Pin 14) No Connection pin. Not used in the circuit, can be left floating. 15 RST (Pin 15) Reset pin. Used to reset the device when pulled low. 16 RST (Pin 16) Reset pin (used in some configurations). If not needed, it can be left floating.20 FAQ About LIS3MDLTR:
