Hi,

I have 4 INA219 connected to single I2C SDA and SCL line - like in a fanout way. What pull up resistors on SDA & SCL line I should use to get the values for all 4 INAs?

Thanks,

Tanveer

Hi Tanveer,

The value of the pull-up resistors don't depend on the number of devices connected the bus, but more so the speed of operation. We generally recommend 3.3k as per the datasheet for fast-mode.

Best,
