LSM6DSRXTR 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 | bidirectional | Serial data output (SDO) for SPI 4-wire, and the I²C least significant address bit (SA0), which gives address 1101011b when tied to Vdd_IO and 1101010b when tied to GND. |
| 2 | SDx | bidirectional | Must be connected to Vdd_IO or GND in Mode 1, carries the I²C master serial data (MSDA) in Mode 2, and carries the auxiliary SPI serial data input (SDI) and 3-wire SDO in Modes 3/4; it has no internal pull-up unless SHUB_PU_EN = 1. |
| 3 | SCx | bidirectional | Must be connected to Vdd_IO or GND in Mode 1, carries the I²C master serial clock (MSCL) in Mode 2, and carries the auxiliary SPI serial port clock (SPC_Aux) in Modes 3/4. |
| 4 | INT1 | bidirectional | Programmable interrupt 1 output; it must be set to Vdd_IO when used as a MIPI I3CSM pure slave, and when left floating it has an internal pull-down and I²C/I3C are both active. |
| 5 | Vdd_IO | power_in | Power supply for the I/O pins, with a 100 nF filter capacitor recommended. |
| 6 | GND | power_in | 0 V supply. |
| 7 | GND | power_in | 0 V supply. |
| 8 | Vdd | power_in | Analog power supply, specified at 1.71 V to 3.6 V, with 100 nF decoupling capacitor placed as close to the pin as possible. |
| 9 | INT2 | bidirectional | Programmable interrupt 2 (INT2) or data enable (DEN); in Mode 2 it also serves as the I²C master external synchronization signal (MDRDY), and by default its output is forced to ground. |
| 10 | OCS_Aux | input | Leave unconnected in Modes 1 and 2; in Modes 3 and 4 it is the auxiliary SPI 3/4-wire interface enable, with no internal pull-up by default. |
| 11 | SDO_Aux | output | Connect to Vdd_IO or leave unconnected in Modes 1 and 2; in Mode 3 (3-wire aux SPI) leave unconnected, and in Mode 4 it is the auxiliary SPI 4-wire serial data output (SDO_Aux). |
| 12 | CS | input | I²C/SPI mode selection: 1 selects SPI idle mode with I²C communication enabled, and 0 selects SPI communication mode with I²C disabled; default has an internal pull-up. |
| 13 | SCL | bidirectional | I²C/MIPI I3CSM serial clock (SCL) or SPI serial port clock (SPC) in all modes; for I²C it must be pulled up to Vdd_IO through external resistors. |
| 14 | SDA | bidirectional | I²C/MIPI I3CSM serial data (SDA), SPI serial data input (SDI), or 3-wire SPI serial data output (SDO); for I²C it must be pulled up to Vdd_IO through an external resistor. |
