BMI088

Bosch Sensortec · Attitude Sensor/Gyroscope · LGA-16(3x4.5)

BMI088 from Bosch Sensortec, in a LGA-16(3x4.5). 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 INT2 bidirectional Accelerometer interrupt pin #2 (INT2_ACCEL). Digital I/O. If unused, leave unconnected (DNC).
2 NC unconnected No connect. Tied to GND in the reference connection diagrams.
3 VDD power_in Main power supply for analog and digital domains. Operating range 2.4 V to 3.6 V. Decouple with 100 nF to GND.
4 GNDA power_in Ground reference for the analog (VDD) domain.
5 CSB2 input SPI chip select for the gyroscope (active low). In I2C mode this pin is DNC (float).
6 GNDIO power_in Ground reference for the digital I/O (VDDIO) domain.
7 PS input Protocol select for the gyroscope. Tie to GND to select SPI, tie to VDDIO to select I2C.
8 SCL/SCK input Serial clock. Acts as SPI SCK in SPI mode, or I2C SCL in I2C mode.
9 SDA/SDI bidirectional Serial data. I2C: SDA serial data I/O; SPI 4-wire: SDI serial data input; SPI 3-wire: SDA serial data I/O.
10 SDO2 output SPI serial data output for the gyroscope (MISO). In I2C mode this pin is the gyroscope I2C address select (A0_GYRO); tie to GND for default address.
11 VDDIO power_in Digital I/O supply voltage. Operating range 1.2 V to 3.6 V. Decouple with 100 nF to GND.
12 INT3 bidirectional Gyroscope interrupt pin #1 (INT3_GYRO). Digital I/O. If unused, leave unconnected (DNC).
13 INT4 bidirectional Gyroscope interrupt pin #2 (INT4_GYRO). Digital I/O. If unused, leave unconnected (DNC).
14 CSB1 input SPI chip select for the accelerometer (active low). In I2C mode tie to VDDIO or leave DNC (float); the accelerometer defaults to I2C when CSB1 is high at power-up.
15 SDO1 output SPI serial data output for the accelerometer (MISO). In I2C mode this pin is the accelerometer I2C address select (A0_ACCEL); tie to GND for default address.
16 INT1 bidirectional Accelerometer interrupt pin #1 (INT1_ACCEL). Digital I/O. If unused, leave unconnected (DNC).
