About this item

The Adafruit BMP390L is a high-precision barometric pressure sensor and altimeter, ideal for applications requiring accurate altitude measurements. It offers a relative accuracy of ±3 Pascals (approximately ±0.25 meters) and a temperature measurement accuracy of ±0.5°C. The sensor supports both I²C and SPI interfaces, providing flexibility for various projects. Its compact design includes a 3.3V regulator and level shifting, ensuring compatibility with 3V and 5V logic microcontrollers. The board features the STEMMA QT / Qwiic connector, enabling easy, solderless integration with development boards. This makes it suitable for drones, wearables, and environmental monitoring systems.
