Bosch Sensortec · Sensors, Transducers · 10-WFLGA

BMP390 from Bosch Sensortec, in a 10-WFLGA. 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 VDDIO power_in Digital interface supply VDDIO, range 1.2 V to 3.6 V.
2 SCK input Serial clock input for SPI (SCK) and I²C (SCL); SCK input low/high levels are referenced to VDDIO.
3 VSS power_in Ground (GND).
4 SDI bidirectional Serial data input in SPI 4-wire mode, data input/output in SPI 3-wire mode, and SDA in I²C, which is open-drain and needs an external pull-up to VDDIO.
5 SDO bidirectional Serial data output in SPI 4-wire mode (hi-Z in 3-wire mode, where it is not connected), and I²C slave address LSB (SA0), which must not be left floating.
6 CSB input Chip select, active low, with internal pull-up to VDDIO; connect to VDDIO to select I²C.
7 INT output Interrupt output to the host; push-pull and active high after power-on or soft reset, configurable via INT_CTRL.
8 VSS power_in Ground (GND).
9 VSS power_in Ground (GND).
10 VDD power_in Main analog supply VDD, range 1.65 V to 3.6 V.
