I2C / SPI BMP280 3.3V Digital Module Replace BMP180 Bmp085 Temperature Barometric Pressure Sensor Module
BMP280, the precision sensor from , is soldered onto PCB. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface
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. 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! BMP280 Features Package 2.5 mm x 2.5 mm x 0.93 mm metal lid LGA Digital interface I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz) Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V VDDIO interface voltage range: 1.2 V to 3.6 V 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...+85 C, 0...100 % rel. humidity, 300...1100 hPa- Humidity sensor and pressure sensor can be independently enabled/disabled
