Frequently Asked Questions

Q: Is the BMP390 sensor module compatible with Arduino in addition to STM32?

A: Yes! The BMP390 atmospheric pressure sensor module supports both I2C and SPI interfaces, making it compatible with a wide range of microcontroller platforms including Arduino, ESP32, Raspberry Pi, and STM32. Most popular platforms have readily available libraries for the BMP390 chip.

Q: What is the difference between I2C and SPI mode on this sensor module?

A: I2C mode uses just two data lines (SDA and SCL), making it great for connecting multiple sensors on the same bus with minimal wiring. SPI mode uses four lines and offers faster data transfer speeds, which is beneficial in time-sensitive or high-throughput applications. This BMP390 module supports both, so you can choose whichever best suits your project.

Q: Can this BMP390 module be used for altitude measurement?

A: Absolutely. Because atmospheric pressure decreases with altitude, the BMP390's high-precision pressure readings can be converted into accurate altitude estimates. This makes it a popular choice for drones, weather stations, and outdoor navigation devices.
