The MaxSerial is a MAX232 based serial board compatible with the Arduino environment.
I'm pleased to offer these as a kit, bare PCB, and fully assembled. Use the below options to purchase with-out the optional 3.3 volt supply or explore your other options.

I'd like to introduce you to my latest idea, the USB7. 6 digits of 7 segment awesomeness all controllable from a USB virtual com port (via AVR-CDC). You send it numbers, it displays them, what could be easier?
The protocol is very simple; the device accepts a string of numbers, '+', '-', '.', space, and upper/lower hex digits (A-E). The device will buffer up to 6 characters to display. When you send a newline or carriage return (0x0A or 0x0D) the display will update with the buffered data. Any other character is thrown away. It is important to remember that decimals take up no character space because they share a digit with the previous number. This means you can't start a string with a '.', you must first send a character (even space) then the '.'.
After the jump I'll set it up to show my download speed using LCD Smartie.

I, and some others it seems, have spotty results talking to the "official" s and their Freeduino counterparts. To that end, I present a max232 based design, complete with Diecimila layout and DTR reset.

Unsatisfied with everything else, I present the simple, single-sided, breadboardable, FT232RL based USB to TTL Serial converter.
I know you're thinking "But everyone under the sun makes an FT232 kit!", and you're right. But they all suffer from a selection of problems:
The answer of course is to design a simple, roomy, single sided board, with a DIP like fit.

makes a number of rather nice serial (and USB based) LCD and VFDs. What they do not make, are inexpensive LCDs. Thankfully, hacking serial onto a cheap parallel LCD is sometimes almost as good.
