Yeah, I'd suggest 2 pullups and 1 MOSFET so a limiting resistor was not needed, thought I was thinking the latter would be available in through hole if space permitted (since you were noting the 0603 size concerns). But, if the space is so tight, skipping the resistor is prudent. JimReceived on 2020-07-12 07:00:03
