  • I bought the Breakout-PCF8575, however I'm not sure how prepare it to interface it with the Arduino, in some datasheets the A0, A1 and A2 are wired to ground; SCL and SDA, I understand are connected to an Arduino port via pull-up resistor, my question is: Do I need to solder the pull-up resistors in your Breakout-PCF8575 in the R1, R2, R3 holes?

    Additionally, do I need to make a connection between center pin and the right pin in every A0, A1, A2, if I want to have these pins to ground?

    Thank you
