The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm, and two mounting holes 3.5mm. Specifications: VDD main supply voltage range: 1.71 V to 3.6 V VDDIO interface voltage range: 1.2 V to 3.6 V Digital interface: I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz) Current consumption 1.8 uA @ 1 Hz humidity and temperature 2.8 uA @ 1 Hz pressure and temperature 3.6 uA @ 1 Hz humidity, pressure and temperature 0.1 uA in sleep mode Operating range -40 to 85 C, Humidity: 0-100%, Pressure: 300-1100. Humidity sensor and pressure sensor can be independently enabled/disabled Default setting of the board single power rail Vdd=Vdd_IO (solder link GS1) pull-ups resistors (R2, R3) 10k protocol selector resistor 0ohm (R1) decoupling capacitors 0.1uF on both power supply pins Vdd & Vdd_IO If you connect board to both power rails VDD_IO 1.8V and VDD 3.3V be sure to remove the power rail jumper GS1. Package : 2* BME280 Atmospheric Pressure Sensor Temperature Humidity Sensor Breakout Product Features BME280 is a Temperature, Humidity & Pressure Sensor breakout board. Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V BME280 is a precision sensor, is soldered onto PCB. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface. Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz). Pressure: 300-1100 hPa; Temperature: -40 to +85°C; Humidity: 0-100%. This precision sensor is used for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy. Shipping We do not ship to a different address.
