on whath board can i find a max32 chips,to build one bye my self?

[drewmerc]

you can get usb ones cheap off ebay http://www.ebay.com/sch/i.html?_trkparms...p=15&_sc=1
or if you really want to build one you can get free samples from maxim-ic, i'd suggest a max233 (not a 232) to remove the need for caps

[drewmerc]

not with a max232 chip as a max232 is just a level shifter
