ISM330DHCXTR 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 | SPI 4-wire serial data output (SDO) and I²C least significant bit of the device address (SA0); default input without pull-up, pull-up enabled with SDO_PU_EN = 1 in reg 02h. |
| 2 | SDx | bidirectional | Mode 1: connect to Vdd_IO or GND; Mode 2: I²C serial data master (MSDA); Mode 3/4: auxiliary SPI 3/4-wire serial data input (SDI) and 3-wire serial data output (SDO). |
| 3 | SCx | bidirectional | Mode 1: connect to Vdd_IO or GND; Mode 2: I²C serial clock master (MSCL); Mode 3/4: auxiliary SPI 3/4-wire serial port clock (SPC_Aux). |
| 4 | INT1 | bidirectional | Programmable interrupt 1 (default input with pull-down); leave unconnected or use external pull-down during power-on, avoid pull-up. |
| 5 | Vdd_IO | power_in | Power supply for I/O pins; a 100 nF filter capacitor is recommended. |
| 6 | GND | power_in | 0 V supply. |
| 7 | GND | power_in | 0 V supply. |
| 8 | Vdd | power_in | Power supply for the device core (analog supply 1.71 V to 3.6 V); a 100 nF filter capacitor is recommended. |
| 9 | INT2 | bidirectional | Programmable interrupt 2 (INT2) / data enable (DEN) / I²C master external synchronization signal (MDRDY) in Mode 2; default output forced to ground, external pull-up not recommended. |
| 10 | OCS_Aux | input | Auxiliary SPI 3/4-wire interface enable in Mode 3/4; in Modes 1 and 2 leave unconnected and soldered to PCB. |
| 11 | SDO_Aux | bidirectional | Auxiliary SPI 4-wire serial data output (SDO_Aux) in Mode 3/4 (leave unconnected for 3-wire); in Modes 1 and 2 connect to Vdd_IO or leave unconnected. |
| 12 | CS | input | I²C/SPI mode selection (1: SPI idle mode / I²C communication enabled; 0: SPI communication mode / I²C disabled). |
| 13 | SCL | bidirectional | I²C serial clock (SCL) / SPI serial port clock (SPC). |
| 14 | SDA | bidirectional | I²C serial data (SDA) / SPI serial data input (SDI) / 3-wire interface serial data output (SDO). |
