LSM6DSMTR from STMicroelectronics, in a LGA-14(2.5x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDO/SA0 | output | SPI 4-wire interface serial data output (SDO) or I2C least significant bit of the device address (SA0). |
| 2 | SDx | bidirectional | I2C serial data master (MSDA) in Mode 2, Auxiliary SPI 3/4-wire interface serial data input (SDI) and 3-wire serial data output (SDO) in Modes 3/4, or connect to VDDIO or GND in Mode 1. |
| 3 | SCx | input | I2C serial clock master (MSCL) in Mode 2, Auxiliary SPI 3-wire interface serial port clock (SPC_Aux) in Modes 3/4, or connect to VDDIO or GND in Mode 1. |
| 4 | INT1 | output | Programmable interrupt 1 output. |
| 5 | VDDIO | power_in | Power supply for I/O pins with recommended 100 nF filter capacitor. |
| 6 | GND | power_in | Ground (0 V supply). |
| 7 | GND | power_in | Ground (0 V supply). |
| 8 | VDD | power_in | Power supply with recommended 100 nF filter capacitor. |
| 9 | INT2 | output | Programmable interrupt 2 (INT2) output, data enable (DEN) input, or I2C master external synchronization signal (MDRDY) input depending on mode and register configuration. |
| 10 | OCS_Aux | input | Auxiliary SPI 3/4-wire interface chip select enable; leave unconnected in Modes 1 and 2. |
| 11 | SDO_Aux | output | Auxiliary SPI 4-wire interface serial data output (SDO_Aux); leave unconnected in 3-wire mode and in Modes 1 and 2. |
| 12 | CS | input | I2C/SPI mode selection input (high = SPI idle mode / I2C communication enabled; low = SPI communication mode / I2C disabled). |
| 13 | SCL | bidirectional | I2C serial clock (SCL) or SPI serial port clock (SPC) depending on interface mode. |
| 14 | SDA | bidirectional | I2C serial data (SDA), SPI serial data input (SDI), or 3-wire interface serial data output (SDO) depending on interface mode. |
