Hello,
What is the load capacitance of BMP388 over the i2c line?

Helo sourav,
Could we know why you need this information, I2C communication failed? The max value is 400pF.

Hello.
Thanks for the instant reply. My planning is to separate the sensor from mcu board and make the communication using I2C via wire. However, on the separate board there will be other sensor as well in the same bus line. How long I could send the data using wiring, I need the load capacitance in the bus channel to calculate the loading.
My targeted frequency is 400Khz. However, 100Khz can also be a choice.
Thanks a lot.

Hello sourav,
As you separate the sensor from mcu board and make the communication using I2C via wire, the connection should be as short as possible.
