Part Number: INA219

Hi Sir,

Could you please help to suggest pull up/down resistor for below pin?

- A0/A1 pull up and pull down resistor suggestion?

- SCL/SDA pull up resistor, 4.7K ohm or 10K ohm are suitable for INA219?

    Hi Anne,

    A0/1 pins can be directly connected to ground or supply. If you want to do so through  a resistor, its value can be anywhere between 0 and 100K.
    The most common value for pull up on SDA and SCL is anywhere between a couple to a few 10's of KOhm; either of your choices are fine.
