Schematic and Layout |
The BMP280 atmospheric pressure sensor module uses the I²C standard for communication, making it easily compatible with most existing development boards.
The presence of power supply voltage on the I²C 3V3 port is indicated by the "PWR LED" located on the module.
For cases where power consumption needs to be minimized, the "PWR LED" can be disabled using the "PWR LED DISABLE" jumper located on the back of the PCB.
The I²C address of the sensor can be modified using the jumper on the back of the PCB. By default, the jumper is open (address 0x77), and it can be soldered (changing the address to 0x76).
The I²C 3V3 connectors are compatible with Qwiic (SparkFun) and STEMMA QT (Adafruit) standards.
Power Supply Voltage: 3.3V DC
Communication Protocol: I²C
I²C Addresses: 0x77 (default - open jumper) or 0x76 (closed jumper)
I²C 3V3 Connector Type: SH 4P
I²C 3V3 Connector Pitch: 1mm
PCB Dimensions: 20mm x 19.4mm
*The BMP280 sensor datasheet is available in PDF format in the DOWNLOADS section.
