SparkFun Micro Pressure Sensor - BMP581 i2c address q

Sensors Environmental

I recently bought this board and everything works fine but I noticed when I run a I2C scan on startup it finds two addresses, 0x47 (the BMP sensor) and 0x7E which I am wondering what that is ? I was using a SF blackboard (uno).

thanks

Not sure - does the 2nd address (0x7E) appear with the BMP sensor disconnected?

No, the bmp sensor is the only sensor plugged in using the qwiic cable

I tested a full size version of the bmp581 board https://www.sparkfun.com/products/20170 and it shows the same results:

9:02:24.402 → Scanning…

19:02:24.402 → I2C device found at address 0x47 !

19:02:24.402 → I2C device found at address 0x7E !

19:02:24.402 → done

Datasheet covers this, check that out.

thanks !

I tried scanning my BMP581, but the scan failed. All the wires are connected. The power is on. Everything I know to check was checked and it should work.
