Nice keypad

Reviewer: from Highlands Ranch, CO

Very nice keypad. Top surface is a matte finish, so it won't show fingerprints and such. Buttons have a firm, tactile feedback. I'm using one combined with the EDE-1144 keypad controller IC.

Reviewer: from FL USA

I had bought this keypad from *ameco *lectronics many years ago for $5.95. I set out to design a system around this keypad because it was so nice. By the time I was ready to order a few hundred they saw the "STAMP" people buying them up like crazy and felt they needed to raise the price. It sold for, and still is I think over $16 from them. This is a good buy. FYI I saw this exact keypad on a bunch of Slot Machines last year. I have not bought from those other guys now for years, and won't anymore.

Kepad and Encoder IC

Reviewer: from GREENFIELD, MA US

I purchased this keypad along with the ede-1144 IC and
A Serial Interface. I assebeled all of this together in a Radio Shack enclosure with a small battery pack. plugged it into my computer and loaded a com port monitor program which displayed exactly what the encoder Ic Output diagram said.
