rs485 by using max485

i have read an article about the Mini2440 UARTs TTL level which is(3.3v)
"http://www.esky-sh.com/bbs//viewtopic.php?f=6&t=243";
my question:
is it possible to connect Max485 on (CON1-CON3)

I would look at the datasheet to confirm if the MAX485 will work properly
with 3V3 logic levels.

I think a better part would be the MAX3485 which works with 3.3V and 5V
logic levels.

Good luck.
