This version comes with headers pre-soldered for easy breadboard use or direct wiring.\n\nThe breakout supports both I²C (5 V tolerant with on-board pull-up resistors to 3.3 V) and SPI (3.3 V) interfaces. It draws less than 1 mA during measurements and idles below 5 µA, making it well suited for battery-powered weather stations and environmental monitoring.\n\nKey Features\n\n\nThree-in-One Sensor – Pressure, humidity, and temperature on a single breakout\n\nI²C and SPI Interfaces – I²C is 5 V tolerant; SPI operates at 3.3 V\n\nPre-Soldered Headers – Ready for breadboard or direct connection\n\nUltra-Low Power – Less than 1 mA active, below 5 µA idle\n\n\nSpecifications\n\n\nOperating Voltage – 3.3 V\n\nPressure Range – 30–110 kPa (relative accuracy ±12 Pa, absolute accuracy ±100 Pa)\n\nHumidity Range – 0–100% RH (±3% accuracy from 20–80% RH)\n\nTemperature Range – −40 °C to +85 °C\n\nAltitude Range – 0–9.2 km (relative accuracy ~1 m at sea level)\n\n\nIdeal For\n\nWeather stations and environmental monitoring\nIndoor/outdoor navigation and altitude estimation\nHome automation and HVAC systems\nPersonal health and wellness monitoring\n\n\nPackage Contents\n\n1× SparkFun BME280 Atmospheric Sensor Breakout (with headers)\n\n\nResources\n\nHookup Guide\nSchematic (PDF)\nEagle Files\nBME280 Datasheet (PDF)\nHardware Design (GitHub)\nArduino Library (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":2302,"title":"Default Title","sku":"SF-SEN-13905","price":46.08,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
