Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SDO/SA0 | bidirectional | SPI 4-wire interface serial data output (SDO) / I2C least significant bit of the device address (SA0). Function is muxed based on selected serial interface mode. |+| 2 | SDx | bidirectional | Mode 1: connect to VDDIO or GND. Mode 2: I2C serial data master (MSDA). Mode 3/4: auxiliary SPI 3/4-wire serial data input (SDI) and SPI 3-wire serial data output (SDO). |+| 3 | SCx | bidirectional | Mode 1: connect to VDDIO or GND. Mode 2: I2C serial clock master (MSCL). Mode 3/4: auxiliary SPI 3/4-wire serial port clock (SPC_Aux). |+| 4 | INT1 | output | Programmable interrupt 1 output in I2C and SPI modes. Used to signal events such as data-ready, wakeup, tap, free-fall, etc. |+| 5 | VDDIO | power_in | Power supply for I/O pins. Recommended 100 nF filter capacitor to GND. |+| 6 | GND | power_in | 0 V supply (ground reference). |+| 7 | GND | power_in | 0 V supply (ground reference). |+| 8 | VDD | power_in | Analog power supply, 1.71 V to 3.6 V. Recommended 100 nF filter capacitor to GND. |+| 9 | INT2 | bidirectional | Programmable interrupt 2 (INT2) / Data enable (DEN). In Mode 2 also serves as I2C master external synchronization signal (MDRDY). |+| 10 | OCS_Aux | input | Mode 1/2: leave unconnected (soldered to PCB). Mode 3/4: auxiliary SPI 3/4-wire interface enable (chip select). |+| 11 | SDO_Aux | bidirectional | Mode 1/2: connect to VDD_IO or leave unconnected. Mode 3/4: auxiliary SPI 4-wire serial data output (SDO_Aux); leave unconnected when using auxiliary SPI 3-wire interface. |+| 12 | CS | input | I2C/MIPI I3C/SPI mode selection. 1: SPI idle mode / I2C/MIPI I3C communication enabled. 0: SPI communication mode / I2C/MIPI I3C disabled. |+| 13 | SCL/SPC | input | I2C/MIPI I3C serial clock (SCL) / SPI serial port clock (SPC). Muxed function based on selected serial interface. |+| 14 | SDA/SDI/SDO | bidirectional | I2C/MIPI I3C serial data (SDA) / SPI serial data input (SDI) / SPI 3-wire interface serial data output (SDO). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | LGA-14(2.5x3) |+| Category | Sensor |+| Pins | 14 |++## Ordering variants++- `LSM6DSRTRLSM6DSR`+- `LSM6DSRTR`++## CAD (KiCad official)++- Symbol: `LSM6DSRTR`+- Footprint: `Package_LGA:Bosch_LGA-14_3x2.5mm_P0.5mm`+- 3D model: LGA-14(2.5x3) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lsm6dsrtr.pdf) (166 pp, sha256 `7f08c9bc2ede9374`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
