The Adafruit DPS310 is a high-precision barometric pressure and altitude sensor from Infineon, mounted on a breakout board with STEMMA QT / Qwiic connectors for solderless I2C wiring. It delivers ±1 hPa absolute accuracy and up to ±0.002 hPa relative precision in high-precision mode — equivalent to detecting altitude changes as small as 2 cm.

The sensor includes a built-in temperature sensor (±0.5°C accuracy) and configurable oversampling with an internal low-pass filter for the lowest-noise readings. It operates over a wide range of 300–1200 hPa and -40°C to 85°C, and supports both I2C and SPI interfaces. The breakout includes level shifting for use with 3.3V or 5V logic.
