this is mostly a stupid check for me . . .
I want to protect my tx/rx lines with resistors, so is this correct?
txA --- 1.18k resistor ---- rxB
rxA --- 1.18k resistor ---- txB
gndA ------------------------- gndB
anyone know how much current the UART for an ATmega needs? I couldn't find it on the datasheet, although Im sure its hidden somewhere in its 400+ pages of glory . . .
(and in case you were wondering, the 1.18k resistor was cheaper than the 1k resistor for 0402 smd)
