The BMP585 from Bosch is a ported barometric pressure and temperature sensor featuring a tube attachment point for differential or remote pressure measurements. It delivers exceptional precision with altitude noise as low as 1 cm (0.08 Pa), making it one of the most precise pressure sensors in the Bosch lineup.

The BMP585 is software and firmware compatible with the BMP580/BMP581 family but adds a port for tube attachment. It supports both I2C and SPI interfaces, with STEMMA QT / Qwiic connectors for solderless I2C connections. The breakout board includes a 3.3V regulator and level shifting for use with both 3V and 5V microcontrollers.
