Hey guy, give it a rest!  This forum is not for advertising.  You got
your one free post, now go away like a good little boy.

From the web site: "The importance issue of the board well work for days in
testing." Which is quite remarkable considering the complete lack of
decoupling on a 60 MHz processor.

Not recommended. I prefer Leon Heller's design:

We apply TWO capacitors for the decoupling capacitors for the 3.3V supply,
another capacitor decouples
the 1.8V supply. They are  closed to the supply and ground pins.
The connections is made with wide tracks to minimise inductance.

By this statement I conclude besides a @#$%& spammer (BTW I hate
spammers with all my guts - I'd hardly buy anything advertised this way)
you know nothing about the matter and this "work for days in testing" is
due much more to the processor's resilience than your design quality.

                               ^^^^^^^^^^^^^^

Isn't this why SPAMMERS keep SPAMMing ??
They know sooner or latter people will buy, so they keep SPAMMing.

Their model works and they keep making money, so they keep SPAMMing.


DOH !

MyLinux,

After months of asking stupid questions...do you really think anyone is
going to buy anything off you? You have well and truely proved to everyone
that you don't know s%*t from clay. Maybe you could sell freshly squeezed
orange juice on the side of the street? In fact no forget that idea...just
go away...
