Does anybody make a cheap single-board computer with microcontroller and LCD display, like an AVR Butterfly except that the LCD is easy to use? The Butterfly's LCD is segment-addressable and if you want digits or characters, you have to create them yourself. A 5.0-volt power supply (instead of the Butterfly's 3 V) would also be handy since I have to have 5.0 V for the equipment to which I'm interfacing. Thanks!
Alternative to AVR Butterfly?

The ATmega169P can run at 5V.

I should add that I'm not looking for an LCD exactly like theirs. All I need is the ability to display about 6 digits.

The ATmega169P can run at 5V.That's a thought. Or I may use a low-cost alpha LCD and a microcontroller and make my own board.

The ATmega169P can run at 5V.$5 16x2? Where? Mouser has a $6 8x2. Almost got it, but no spec sheet to be found *anywhere*, and I'm a beginner... Thanks, Michael

Thanks... What country are you in? And why are you giving them to the EE department instead of selling them and donating the proceeds to charity, just curious? Thanks again, Michael mrdarrett@gmail.com
