Hi Florin, Looks very nice, the perferct evaluation board for developers ;)
Some point to concider for even more improvement: - What would be nice is a led or two, but there are four in a combined way and you may run out of pins... - And if you make e.g. jumper 1 to 4 a dip-switch, you can use it as a on/off switch. - And last but not least: it would be nice to have a pushbutton or two, they are more easy to read than a keyboard. With a resistor from 5V to the colums lines will do. - And about those column lines: is there a reason they are on the higher half of port D and not the lower half? The latter can be freed with a character display if you use 4 bit mode... What is the use of the ne555? What will be the size of this shield? And would it be usable on an arduino board?
