At the end of the page, it’s written “We use 10 kΩ resistors for mains powered monitors. The emonTx uses 470 kΩ resistors to keep the power consumption to a minimum, as it is intended to run on batteries for several months.”
Why then not using always 470k for R1 and R2 ?!? are they any other drawbacks ?!?
