I like to make circuit boards with parts that are often wired up on my
prototype boards. This board uses the MAX232, or compatable IC, in standard
configuration to convert TTL/CMOS to RS-232 levels and vice versa. The
connection strip has
holes the same size as a prototype board for quick connection.
Documentation
I am not posting the schematic because it is available from the Maxim MAX232
data sheet on their web site.
