Controlling Parallax 2x16 Serial LCD (Backlit)

I'm very new to basic stamp although I've been doing programming for more than 10 years. I would like to be able to control Parallax 2x16 Serial LCD (Backlit). Which product do you recommend? BS1USB Board looks compact and cool. Will it work?

Download the PBASIC IDE to find out more about that.· There are examples in the documentation for the 2x16 Serial LCD.
The BS1 will work fine, but for just a bit more money you can get a BS2. The PBasic code for them is somewhat easier to work with and they have more program storage space (flash memory).
It would be really nice if Parallax would sell their LCD controller board separate from the LCD (hint hint), or at least as a semi-kit or something where the controller isn't soldered to the LCD (I've just gotten kind of tired of green back lit LCDs).

Are you wanting to display information from your PC?· An exisiting device?· Or are you creating something from scratch?
The display will accept serial data, it doesn't care about the source of that data (Don't connect it directly to your computer's serial port though, the voltage is too high.· You just need to add a serial interface chip, such as the MAX232 series.)
As stated on the product page:
What you will need is some kind of software running on the PC to send your data out one of the serial ports and an adapter to convert that serial data to the TTL (5 volt) level required by the LCD. Typically this is done using a circuit based on the MAX232 chip.
edit: Note that the link was provided for the info, you don't have to make your own RS232 to TTL converter - you can just buy one.
