BMP388 - Precision Barometric Pressure and Altimeter
Pinout
- VIN
Board power input. Adafruit states the onboard regulator takes 3-5VDC and converts it down for the BMP3xx sensor.
Type · powerVoltage · 3-5V DC input - 3Vo
3.3V output from the onboard voltage regulator, available for small external loads.
Type · powerVoltage · 3.3V output, up to 100mA per Adafruit guide - GND
Common ground for power and logic.
Type · groundVoltage · 0V - SCK / SCL
SPI clock input, also I2C clock when using I2C mode. Adafruit states breakout inputs are 3-5V logic-level safe.
Type · signalVoltage · 3-5V logic input - SDO
SPI serial data out / MISO from the BMP3xx to the controller.
Type · signalVoltage · 3.3V logic output, readable by 5V microcontrollers
