Parallax parts

Archiver

Hello Stampers,

This isn't a typical stamp question, but the parallax parts will be hookeed
to a stamp so.............


I bought the parallax (#28005) 418 MHz Keychain transmitter and the (#28004)
418 MHz Receiver.

The documentation that came along says you have to put a solid copper layer
underneath the breadboard connected to the receivers groud (to increase
working distance)

I am past development now and want to build all the stuff permanently inside
a motorhome (RV).

The Stamp and peripherials will be seperated from the receiver and connected
by FTP, the stamp hided away for burglar protection, the receiver somewhere
high in the RV in a ABS plastic box.

What is the best way to design a pcb that supports the tranceiver (in a sil
connector) and contains the 12v to 5v regulator and power supply filtering
circuits , as small and thin as possible.

Of coarse with a range as big as possible :-)

Thanks in advance

Are you going to use an internal antenna or an external antenna from
the enclosure? The ground plane is used as counterpoise(spelling?)
for the antenna. The more copper you have under your antenna the
better it will work. If you really want to pack it in tight use
surface mount parts to construct your circuit. You will need to etch
a PCB or go through a service like www.expresspcb.com. How much
current your +5 volts draws will determine the size of the supply and
how much board space is required.
