RS-232 Circuit
Tuesday, March 31st, 2009Posted in Basic Circuits is a very basic RS-232 driver circuit to use in interfacing your circuits to a PC via serial port. Notice I used the MAX233 integrated circuit, to avoid a mass of capacitors and soldering for the novice. The MAX232 is nearly identical, except for the use of external capacitors. It is a bit cheaper as well, but does not yield such a compact and clean board layout. http://speedofdark.us/pmwiki/pmwiki.php?n=Projects.Interfaces
