Hi eulero,
Thank you for posting on the forum.
All our units with keypad interface are in a matrix style configuration. The display will depend on what you want with it. What communication protocol will yo be using? TTL, RS-232, I2C, or USB? What size of the display would you want? 2x8, 2x16, 2x20, 2x40, 2x20, or 4x40? There are different colours, and there are graphics with 2 different sizes. If you can provide more specifics, I can suggest a unit that will suit you best. An example of what application you will be using it for will be good too.
tnx for your answer ... here the specification

tnx a lot man for your answer.
the protocol i have to use is RS232, for application on embedded system pc104 or rabbit (linux embedded solutions); 2x20 or 2x40 will be sufficient
tnx i wait your answer

eulero,
I can recommend either a LK202-25 or a LK204-25. They both have 5x5 key matrix. Since you are communicating via RS-232, they come as default RS-232. You can also change over to a different communication protocol to I2C or TTL communications.
For more detailed information on these units, you may refer to the manuals.

If you have anymore questions or concerns, please feel free to post them.
Best Regards,
