## Description

This compact Fermion breakout brings the Bosch BMP585 MEMS pressure and temperature sensor to a tiny board for projects where space, power use and reliable environmental sensing matter. It measures barometric pressure for altitude and vertical movement applications, with typical absolute pressure accuracy of ±0.3 hPa.The sensing unit uses a gel-filled housing to help protect the element from water intrusion, high humidity and chemical corrosion while still allowing pressure changes to be measured. That makes it suitable for outdoor monitoring, industrial sites, marine-style environments, UAV altitude hold, indoor floor detection and sports altimeters.Integration is flexible, with I2C, SPI and I3C support through a 2.54 mm pin header socket. Built-in FIFO buffering and a configurable IIR filter can smooth pressure changes caused by wind gusts or vibration before the data reaches your host microcontroller.DFRobot provides open-source libraries for Arduino and Python to help speed up prototyping. The shipping list includes the Fermion BMP585 sensor module and a 10pin-2.54 black single row pin header.Specifications:Operating Voltage: DC 3.3VOperating Current: 200μASleep Current: 2μACommunication Interface: I2C / I3C /SPIInterface Form: 2.54mm Pin Header SocketI2C Address: 0x47 (Default) / 0x46Pressure Measurement Range: 30 ~ 125 kPaTemperature Measurement Range: 0 ~ 65 °CAbsolute Pressure Accuracy: ±0.3 hPa (Typ.)Relative Pressure Accuracy: ±0.06 hPa / 10 kPa (Typ.)Relative Altitude Accuracy: ±0.5 m / 10 kPaTemperature Drift Coefficient: ±0.5 Pa / KPressure Data Resolution: 1 / 64Ultra-Low Noise: < 0.1 Pa (RMS, without low-pass filter enabled)PCB Dimensions: 19×16×3.55 mmMounting Hole Spacing: 14 mmMounting Hole Diameter: 2.0 mm
