Pinout
13| Pin | Name | Functions | Notes |
|---|---|---|---|
| Vin | Power | POWER | Input voltage. Can be 3-5V. |
| 3Vo | 3.3V Output | GND | Output of the on-board 3.3V regulator, up to 100mA available. |
| GND | Ground | GND | Common ground for power and logic. |
| SCL | I2C Clock | I2C | I2C clock line. Has a 10K pullup resistor on board. |
| SDA | I2C Data | I2C | I2C data line. Has a 10K pullup resistor on board. |
| SDO | I2C Address Selection | I2C | Used for I2C address selection when connected to GND or left open. Can be set to 0x19 by connecting it to 3Vo. |
| SCK | SPI Clock | SPI | SPI clock pin, input to the chip. |
| SDI | SPI Data In | SPI | Serial data in / microcontroller out sensor in. For data sent from your processor to the LIS331. |
| SDO | SPI Data Out | SPI | Serial data out / microcontroller in sensor out. 3.3V logic level output. |
| CS | Chip Select | SPI | Drop low to start an SPI transaction, input to the chip. |
| INT | Interrupt Output | GPIO | Can be configured for interrupt on different events such as data availability. |
| I2 | Interrupt Output 2 | GPIO | Second interrupt output pin, can also be used for address selection. |
| NC | No Connect | GND | Mechanical stability pins only. |
